Determine:

a. the program execution time
b. the effective CPI for the machine
c. MIPS rate for the following processors

Answers

Answer 1

Answer:

Execution time is 13.65ms

CPI is 5.46

MIPS is 73.3\ MIPs

Explanation:

Given:

[tex]s = 40MHz[/tex] --- processor speed [Missing from the question]

[tex]\begin{array}{ccc}{Instruction\ Type} & {Instruction\ Count} & {Cycles\ per\ Instruction} & {Integer\ Arithmetic} & {45000} & {4} \ \\ {Data\ Transfer} & {32000} & {6} & {Floating\ point\ arithmetic} & {15000} & {10} & {Control\ Transfer} &{8000} & {3} \ \end{array}[/tex]

Solving (a): The program execution time

First, we solve for (b)

Solving (b): The effective CPI

This is calculated as:

[tex]CPI = \frac{\sum IC * CI}{\sum IC}[/tex]

Where: IC = Instruction Count and CI = Cycles per Instruction

So, the equation becomes:

[tex]CPI = \frac{45000 *4 + 32000 * 6 + 15000 * 10 + 8000 * 3}{45000+32000+15000+8000}[/tex]

[tex]CPI = \frac{546000}{100000}[/tex]

[tex]CPI = 5.46[/tex]

Solving (c): MIPS

This is calculated as:

[tex]MIPS = Speed * \frac{1}{CPI} * \frac{1}{\sum IC}[/tex]

[tex]MIPS = 40 * \frac{1}{5.46} * \frac{1}{100000}[/tex]

[tex]MIPS = \frac{40 * 1 * 1}{5.46*100000}[/tex]

[tex]MIPS = \frac{40}{546000}[/tex]

[tex]MIPS = 0.00007326007[/tex]

Convert to MIPs

[tex]MIPS = 73.3\ MIPs[/tex]

Solving (a): Execution Time

This is calculated as:

[tex]Time = Instructions * CPI * \frac{1}{Speed}[/tex]

[tex]Time = 100000 * 5.46* \frac{1}{40M}[/tex]

[tex]Time = \frac{546000}{40M}[/tex]

[tex]Time = \frac{546000}{40*1000000}[/tex]

[tex]Time = \frac{546000}{40000000}[/tex]

[tex]Time = 0.01365s[/tex]

[tex]Time = 13.65ms[/tex]

Execution time is 13.65ms

When my animal is to old to physically carry her baby what process can I use to still produce her young from her

Answers

Taking care of" is a very human term in the sense of care giving, but so is "parents", because animals do not retain family structures in the form humans do. The vast majority of animals do not recognize family members. Among predators, an aging parent, such as the male lion in a pride, would continue to be taken care of by the females just as they always were, until a stronger outside male ousted it. An aging silverback in a group of gorillas would eventually be challenged and overthrown by one of his sons. When the elder became too infirm to care for itself, it would go off by itself to die. The only animal species that modify their behavior due to familial bonds to accommodate the needs of an aging member of the family are Cetaceans (whales) and Pachyderms (elephants). Whales have been seen to bouy up an ailing member of the pod (an extended family) to keep it from sinking. Elephants have the closest family ties of all animals, the eldest surviving female, the Matriarch of a herd, might be the great, great, great grandmother to the youngest and the others in varying relationships, are mothers, grandmothers, children, sisters, aunts and cousins, the older always taking care of and sheltering the younger. They also shelter and accommodate the older. If one member is sick or too old to keep up, the rest of the herd will slow down to allow the lagging one to keep up. This "caring" behavior has its limitations. The herd will not endanger itself to stay with an ailing member who will never be able to keep up. However, when the Matriarch herself is dying of old age, and the herd is in an area where food and water are abundant, the rest of the herd will stay with her, comfort her with their trunks, caressing her, talking to her, vocalizing over her, never leaving her side. While some are foraging, there will always be a group around her comforting her and expressing their love. (Scientists used to dismiss that term as inapplicable to animals, but the evidence is overwhelming that higher animal species have the same emotions humans do.) The herd will remain with her body, mourning, for several days, and years later will still return to fondle her bones with their trunks. Eventually one of the Matriarch's daughters will be chosen as the one to follow, or even two in which case the herd would divide into two new herds, the daughters and their offspring of each new Matriarch following their own family line.

This question is not complete, the complete question is;

The stagnation chamber of a wind tunnel is connected to a high-pressure air bottle farm which is outside the laboratory building. The two are connected by a long pipe of 4-in inside diameter. If the static pressure ratio between the bottle farm and the stagnation chamber is 10, and the bottle-farm static pressure is 100 atm, how long can the pipe be without choking? Assume adiabatic, subsonic, one-dimensional flow with a friction coefficient of 0.005

Answer:

the length of the pipe is 11583 in or 965.25 ft

Explanation:

Given the data in the question;

Static pressure ratio; p1/p2 = 10

friction coefficient f = 0.005

diameter of pipe, D =4 inch

first we obtain the value from FANN0 FLOW TABLE for pressure ratio of ( p1/p2 = 10 )so

4fL[tex]_{max}[/tex] / D = 57.915

we substitute

(4×0.005×L[tex]_{max}[/tex]) / 4  = 57.915

0.005L[tex]_{max}[/tex] = 57.915

L[tex]_{max}[/tex] = 57.915 / 0.005

L[tex]_{max}[/tex]  = 11583 in

Therefore, the length of the pipe is 11583 in or 965.25 ft

Answer:

y'(x) = 7 ;

y'(x) = 15x²

Explanation:

Differentiation from first principle :

y = 7x

Formula to obtain derivative from first principle:

y'(x) = lim(h - - > 0) : [y(x + h) - y(x)] / h

Obtain : y(x + h)

y(x) = 7x

y(x + h) = 7(x + h)

Substitute into formula :

y'(x) = lim(h - - > 0) : [7(x + h) - 7x] / h

Expand :

y'(x) = lim(h - - > 0) : [7x + 7h - 7x] / h

y'(x) = lim(h - - > 0) : 7h/ h

y'(x) = 7

2.)

y = 5x³

y'(x) = lim(h - - > 0) : [y(x + h) - y(x)] / h

Obtain : y(x + h)

y(x) = 5x³

y(x + h) = 5(x + h)³

Substitute into formula :

y'(x) = lim(h - - > 0) : [5(x + h)³ - 5x³] / h

Expand :

y'(x) = lim(h - - > 0) : [5(x³ + 3x²h + 3xh² + h³) - 5x³] / h

y'(x) = lim(h - - > 0) : [5x³ + 15x²h + 15xh² + 5h³ - 5x³] / h

y'(x) = lim(h - - > 0) : [15x²h + 15xh² + 5h³] / h

y'(x) = lim(h - - > 0) : h(15x² + 15xh + 5h²) / h

y'(x) = lim(h - - > 0) : (15x² + 15xh + 5h²)

y'(x) = 15x²

A company purchases a certain kind of electronic device from a manufacturer. The manufacturer indicates that the defective rate of the device is 3%. 1) The inspector randomly picks 20 items from a shipment. What is the probability that there will be at least one defective item among these 20? 2) Suppose that the company receives 10 shipments in a month and the inspector randomly tests 20 devices per shipment. What is the probability that there will be exactly 3 Shipments each containing at least one defective device among the 20 that are selected and tested from the shipment?​

Answers

Answer:

1) The probability of at least 1 defective is approximately 45.621%

2) The probability that there will be exactly 3 shipments each containing at least 1 defective device among the 20 devices that are tested from the shipment is approximately 16.0212%

Explanation:

The given parameters are;

The defective rate of the device = 3%

Therefore, the probability that a selected device will be defective, p = 3/100

The probability of at least one defective item in 20 items inspected is given by binomial theorem as follows;

The probability that a device is mot defective, q = 1 - p = 1 - 3/100 = 97/100 = 0.97

The probability of 0 defective in 20 = ₂₀C₀(0.03)⁰·(0.97)²⁰ ≈ 0.543794342927

The probability of at least 1 = 1 - The probability of 0 defective in 20

∴ The probability of at least 1 = 1 - 0.543794342927 = 0.45621

The probability of at least 1 defective ≈ 0.45621 = 45.621%

2) The probability of at least 1 defective in a shipment, p ≈ 0.45621

Therefore, the probability of not exactly 1 defective = q = 1 - p

∴ q ≈ 1 - 0.45621 = 0.54379

The probability of exactly 3 shipment with at least 1 defective, P(Exactly 3 with at least 1) is given as follows;

P(Exactly 3 with at least 1) = ₁₀C₃(0.45621)³(0.54379)⁷ ≈ 0.160212

Therefore, the probability that there will be exactly 3 shipments each containing at least 1 defective device among the 20 devices that are tested from the shipment is 16.0212%

Answers

Answer:

The heat flow in 24 hours through the refrigerator door is approximately 1,608.57 BTU

Explanation:

The given parameters are;

The duration of the heat transfer, t = 24 hours = 86,400 seconds

The area of the refrigerator door, A = 30.0" × 58.0" = 1,740 in.² = 1.122578 m²

The material of the insulator in the door = Cellulose fiber

The thickness of the insulator in the door, d = 2.0" = 0.0508 m

The temperature inside the fridge = 38° F = 276.4833 K

The temperature of the room = 78°F = 298.7056 K

The thermal conductivity of cellulose fiber = 0.040 W/(m·K)

By Fourier's law, the heat flow through a by conduction material is given by the following formula;

[tex]\dfrac{Q}{t} = \dfrac{k \cdot A \cdot (T_2 - T_1) }{d}[/tex]

[tex]Q = \dfrac{k \cdot A \cdot (T_2 - T_1) }{d} \times t[/tex]

Therefore, we have;

[tex]Q = \dfrac{0.04 \times 1.122578 \times (298.7056 - 276.4833 ) }{0.0508} \times 86,400 =1,697,131.73522[/tex]

The heat flow in 24 hours through the refrigerator door, Q = 1,697,131.73522 J = 1,608.5705140685 BTU

c)  0.37 day^-1

d)

i) volume of wasted solid = 783 m^3/day

ii) mass of wasted solid = 7830 kg/day

e) 1.12

Explanation:

Given data :

Flow ( Q ) = 17500 m^3/day

BOD 5 ( influent ) = 1000 mg/L

BOD 5 ( efficient ) = 120 mg/L

mean cell residence time ( ∅ c ) = 6-day

MLSS concentration ( X ) = 5500 mg/L

a) Determine the hydraulic retention time and volume of the activated sludge

i) Hydraulic retention time ( OH ) we will use the relation below

X = [tex]\frac{OcY(sin-s)}{OH(1 + Kdθc)}[/tex]  

5500 = [tex]\frac{6*0.6(1000-120)}{OH(1 + 0.03*6)}[/tex] .  therefore  OH = 0.488 days ≈ 11.72 hour

ii) volume of the activated sludge  using the relation below

 OH = V / Q

V = OH * Q

  = 0.488 * 17500

  = 8542.38 m^3

b) Determine the  volumetric loading rate in kg BOD,/m- day to the reactor

loading rate = ( Q * Sin ) /  V

                     = ( 17500 * 1000 ) / 8542.38

                     = 2.05 kg/m^3.day

c) Determine The F/M ratio in the reactor

F/M ratio :  F/M = ( Q .sin ) / VX

                         = ( 17500 * 1000 ) / ( 8542.37 * 5500)

                         = 0.37 day^-1

d) Determine The mass and volume of solids wasted each day, at an underflow solids concentration

The dry weather average flow rate for a river is 8.7 m3/s. During dry weather flow, the average COD concentration in the river is 32 mg/L. An industrial source continuously discharges 18,000 m3/d of wastewater contains an average 342 mg/L COD concentration into the river. What is the COD mass loading in the river upstream of the industrial source discharge

Answers

Answer:

6156 kg /day

Explanation:

Determine the COD mass loading in the river upstream of the industrial source discharge

Given data:

Flow rate of river = 8.7 m^3/s

Average COD concentration in river = 32 mg/L

Industrial source continuous discharge ( Qw )= 18,000 m^3/d

Yw = 342 mg/l

since :

1 m^3 = 1000 liters

Qw = 18 * 10^6  liters = ( 18 million per day )

Hence the COD mass loading

= Yw * Qw

= 342 * 18 liters

= 6156 kg /day

For a con-vection heat transfer coefficient of 15 W/m2·K, determinethe rate of heat loss from this man by convection in still airat 20°C. What would your answer

Answers

Answer:

Rate of Heat Loss = 336 W

Explanation:

First, we will find the surface area of the cylinder that is modelled as the man:

[tex]Area = A = (2\pi r)(l)[/tex]

where,

r = radius of cylinder = 30 cm/2 = 15 cm = 0.15 m

l = length of cylinder = 170 cm = 1.7 m

Therefore,

[tex]A = 2\pi(0.15\ m)(1.7\ m)\\A = 1.6\ m^2[/tex]

Now, we will calculate the rate of heat loss:

[tex]Rate\ of\ Heat\ Loss = hA\Delta T[/tex]

where,

h = convective heat tranfer  coefficient = 15 W/m²K

ΔT = Temperature difference = 34°C - 20°C = 14°C

Therefore,

[tex]Rate\ of\ Heat\ Loss = (15\ W/m^2K)(1.6\ m^2)(14\ K)\\[/tex]

Rate of Heat Loss = 336 W

A storage tank is purged continuously with a stream of nitrogen. The purgestream leaving the tank is saturated with the product stored in the tank. A majorpart of the product lost in the purge could be recovered by installing a scrubbingtower to absorb the product in a solvent. The solution from the tower could befed to a stage in the production process, and the product and solvent recoveredwithout significant additional cost. A preliminary design of the purge recoverysystem has been made. It would consist of:1. A small tower 0.5 m diameter, 4 m high, packed with 25 mm ceramic saddles,packed height 3 m.2. A small storage tank for the solution, 5 m3 capacity.3. The necessary pipe work, pump, and instrumentation.All materials of construction, carbon steel.Using the following data, evaluate whether it would be economical to install therecovery system:1. cost of product £5 per kg,2. cost of solvent 20 p/kg,3. additional solvent make-up 10 kg/d,4. current loss of product 0.7 kg/h,5. anticipated recovery of product 80 per cent,6. additional service(utility) costs, negligible.Other operating costs will be insignificant.

Answers

Answer:

It is economical

Explanation:

Given data for determining

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent makeup = 10 kg/d

current loss of product = 0.7 kg/h

anticipated recovery of product = 80%

additional service ( utility cost ) = negligible

Determine if it is economical to install the recovery system

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent required = 10 kg / d

cost of additional solvent in a day  = £200 / day  ( £20 per kg * 10 kg / d )

product lost = 0.7 kg/h

product recovered = 0.7 * 80% = 0.56 kg/h

therefore product recovered in a day = 0.56 * 24 = 13.44 kg / day

Next :

calculate income generated from product recovery

13.44 kg/day *  £20 /kg =  £268.88 / day

Determine if it is economical

Income - cost

= £268.88 - £200

=  £68.88  ( hence it is economical )
