When a car is travelling at a constant speed, the total drag force acting on the car is equal in magnitude and opposite in direction to the driving force applied by the engine.

This is because the car is not accelerating and therefore the net force acting on it is zero. In order to maintain a constant speed, the engine must apply a force equal in magnitude and opposite in direction to the total drag force. The size of the total drag force depends on various factors such as the shape of the car, the speed of the car, and the air density. In general, at higher speeds, the total drag force increases due to the increased air resistance. When a car is travelling at a constant speed, the total drag force acting on the car is also constant. The size of the drag force depends on factors such as the size and shape of the car, the speed at which it is travelling, and the properties of the medium it is moving through (such as air or water). However, as long as these factors remain constant, the total drag force will also be constant.

"Le Plongeur," the world's inaugural type of machine-powered submarine, was conceived by Henri Dupuy de Lôme and Siméon Bourgeois in 1859.

Through its usage of a steam engine to propel a solitary propeller, the ingenious vessel exemplified modernity as it consumed coal from an inboard bunker to generate steam which activated pistons so as to drive the said propeller beneath the waves.

Furthermore, notable features such as ballast tanks that enabled balancing and alteration of depth, concurrent with a snorkel for air intake whilst submerged, further set "Le Plongeur" apart as a maritime feat of engineering.

The temperature the coil has risen to is approximately 96.64°C.

To find the temperature the coil has risen to, we'll use the temperature coefficient of resistance (TCR) formula:

R2 = R1 × (1 + α × (T2 - T1))

Where R1 and R2 are the initial and final resistances, α is the temperature coefficient of resistance, and T1 and T2 are the initial and final temperatures. In this case, R1 = 200, R2 = 240, α = 0.0039, and T1 = 18°C.

First, rearrange the formula to solve for T2:

T2 = T1 + (R2 / (R1 × α) - 1) / α

Now, plug in the values:

T2 = 18 + (240 / (200 × 0.0039) - 1) / 0.0039

T2 = 18 + (240 / 0.78 - 1) / 0.0039

T2 ≈ 18 + (307.69 - 1) / 0.0039

T2 ≈ 18 + 306.69 / 0.0039

T2 ≈ 18 + 78.64

T2 ≈ 96.64°C

The type of energy that drives the generator of a wind turbine is mechanical energy.

A wind turbine converts the kinetic energy of the wind into mechanical energy. When the wind blows, it causes the turbine's blades to rotate. This rotational motion is the mechanical energy that drives the generator. The rotating blades are connected to a shaft, which in turn connects to a generator. As the blades spin, the mechanical energy is transferred to the generator, where it is converted into electrical energy.

Thus, mechanical energy accurately describes the type of energy involved in the generation process of a wind turbine.

The power required to drive the 42" x 70" Nordberg Gyratory Crusher is approximately 189.97 kW.

To calculate the power required to drive a 42" x 70" Nordberg Gyratory Crusher, we will use the following equation:

Power (P) = Work done per unit time (W) / Time (t)

Given the design throughput of 1,200 tph (tons per hour) and considering the maximum feed size of 1,000 mm and a product where 80% is smaller than 150 mm with a 25 mm throw, we can use the following steps:

1. Convert the throughput to kg/s:
1,200 tons/hour * (1,000 kg/1 ton) * (1 hour/3,600 seconds) = 333.33 kg/s

2. Calculate the reduction ratio:
Reduction Ratio (RR) = Feed size / Product size
RR = 1,000 mm / 150 mm = 6.67

3. Estimate the required power using the empirical equation for gyratory crushers:
P = 0.075 * W * (1 + sqrt(1 + 4 * (RR - 1))) / t
P = 0.075 * 333.33 kg/s * (1 + sqrt(1 + 4 * (6.67 - 1))) / (1/333.33 s)
P ≈ 189.97 kW

At steady state, the temperature at the interface of the two layers is 41°F, and the rate of heat transfer through the wall is 2.48 Btu/h·ft² of surface area.

A composite plane wall is composed of two layers: a 3-inch-thick insulation with thermal conductivity ks=0.029 Btu/h·ft·°R, and a 0.75-inch-thick siding with ks=0.058 Btu/h·ft·°R. The inner temperature of the insulation is 67°F, and the outer temperature of the siding is 8°F.

(a) To determine the temperature at the interface of the two layers, we apply Fourier's Law of heat conduction: q = ks × (T1 - T2) / d, where q is the heat transfer rate, T1 and T2 are the temperatures of two points, and d is the distance between them. Since the heat transfer rate is constant across the wall, we can set up an equation for each layer:

q = 0.029 × (67 - T_interface) / 3
q = 0.058 × (T_interface - 8) / 0.75

Solving these equations simultaneously, we get T_interface = 41°F.

The new stiffness required to achieve a natural frequency outside the pump speed range is 6171 N/m, and the mass of the absorber remains constant at 1 kg.

To solve this problem, we need to use the equation for the natural frequency of a system:

f = (1/2π) * √(k/m)

where f is the natural frequency, k is the spring stiffness, and m is the mass.

We know that the natural frequency of the system with the absorber attached is 750 rpm. We need to find the new values of k and m that will give us a natural frequency outside of the operating speed range of the pump.

First, we need to convert the pump speed range from rpm to Hz:

700 rpm = 11.67 Hz
1040 rpm = 17.33 Hz

Next, we need to find the frequency range that we want to avoid:

fmin = 11.67 Hz
fmax = 17.33 Hz

Now, we can use the equation for the natural frequency to solve for the new values of k and m:

750 rpm = 12.5 Hz

f = (1/2π) * √(k/m)

12.5 Hz = (1/2π) * √(ka/ma)

Squaring both sides, we get:

156.25 = (1/4π^2) * ka/ma

Multiplying both sides by 4π^2, we get:

ka/ma = 625π^2

So, the new values of ka and ma that satisfy the requirement are:

ka = 625π^2 * ma

We don't know the exact value of ma, but we know that the absorber has a mass of 1 kg. So, we can use this value to find ka:

ka = 625π^2 * 1 kg

ka = 6171 N/m

Therefore, the new value of ka that satisfies the requirement is 6171 N/m.

The coefficient of discharge for the given scenario is approximately 0.95.

To find the coefficient of discharge (Cd), we must first calculate the theoretical discharge (Q_theoretical) and the actual discharge (Q_actual).

1. Calculate Q_theoretical using the formula: Q_theoretical = A_gate * √(2 * g * h)
Where A_gate = Area of the gate opening, g = acceleration due to gravity (9.81 m/s²), and h = head of water over the gate (0.3 m).
A_gate = width * height_opening = 0.4 m * 0.1 m = 0.04 m²
Q_theoretical = 0.04 m² * √(2 * 9.81 m/s² * 0.3 m) ≈ 0.283 m³/s

2. Calculate Q_actual using the formula: Q_actual = A_tank * (h_rise / t_rise)
Where A_tank = Area of the rectangular tank, h_rise = rise of water level (0.9 m), and t_rise = time taken for the rise (15 s).
A_tank = 1 m * 1 m = 1 m²
Q_actual = 1 m² * (0.9 m / 15 s) = 0.06 m³/s

3. Calculate the coefficient of discharge (Cd) using the formula: Cd = Q_actual / Q_theoretical

The expected stress that would correspond to a strain of 0.000250 is 182 MPa.

To determine the modulus of elasticity for the material, we need to find the slope of the stress-strain curve between the two given points (a and b).

The slope between points a and b can be calculated using the following equation:

slope = (strain_b - strain_a) / (stress_b - stress_a)

Substituting the values given in the problem, we get:

slope = (0.000630 - 0.000170) / (134 - 35) = 0.00364

Therefore, the modulus of elasticity can be calculated as the slope times the proportional limit, which is given as 200 MPa in the problem:

modulus of elasticity = slope * proportional limit = 0.00364 * 200 = 0.728 GPa

To calculate the expected stress that would correspond to a strain of 0.000250, we can use the following formula:

stress = strain * modulus of elasticity

Substituting the values we have calculated, we get:

The volume of the elastic tank containing 1 kmol of air at 18°C and 225 kPa can be calculated using the ideal gas law:

V = nRT/P

where V is the volume, n is the number of moles, R is the gas constant, T is the temperature, and P is the pressure.

Plugging in the given values, we get:

V = (1 kmol)(8.314 J/mol.K)(291 K)/(225 kPa)

V ≈ 23.86 m³

When the volume is doubled at the same pressure, the new volume becomes 2V, and the ideal gas law gives us:

T₂ = (2V)(P)/(nR)

Plugging in the known values, we get:

T₂ = (2)(23.86 m³)(225 kPa)/(1 kmol)(8.314 J/mol.K)

T₂ ≈ 285.6 K

Converting this temperature to Celsius, we get:

T₂ ≈ 12.5°C

Here is information on image filtering in spatial and frequency domains.

Image filtering in the spatial domain involves applying a filter mask to an image in the time domain to obtain a filtered image. The filter mask or kernel is a small matrix used to modify the pixel values in the image. Common types of filters include the Box filter, Gaussian filter, and Sobel filter.

To apply image filtering in the spatial domain, one can follow the steps mentioned in the prompt, such as converting the image to grayscale, defining a filter, padding the image, and using nested loops to apply the filter.

In contrast, image filtering in the frequency domain involves transforming the image into the frequency domain using a Fourier transform, applying a filter to the frequency domain representation, and then transforming it back to the spatial domain using an inverse Fourier transform.

Both spatial and frequency domain filtering can be used for various image processing tasks such as noise reduction, edge detection, and image enhancement.

Answer:

a)

i) To find the resistance of the circuit, we can use the formula:

Power = (Voltage)^2 / Resistance

Rearranging the formula, we get:

Resistance = (Voltage)^2 / Power

Substituting the given values, we get:

Resistance = (240)^2 / 450 = 127.2 ohms

Therefore, the resistance of the circuit is 127.2 ohms.

ii) To find the reactive power of the circuit, we can use the formula:

Reactive power = (Voltage)^2 x sin(θ)

where θ is the angle between the voltage and current phasors.

Since the load current is leading, the angle θ is negative. We can find the value of sin(θ) using the power factor:

Power factor = cos(θ)

cos(θ) = resistance / impedance

impedance = resistance / cos(θ) = 127.2 / cos(-cos⁻¹(0.8)) = 223.4 ohms

sin(θ) = √(1 - cos²(θ)) = √(1 - 0.64) = 0.8

Substituting the given values, we get:

Reactive power = (240)^2 x 0.8 = 46,080 VAR (volt-ampere reactive)

Therefore, the reactive power of the circuit is 46,080 VAR.

iii) To find the capacitance of the circuit, we can use the formula:

Capacitance = Reactive power / (ω x Voltage^2)

where ω is the angular frequency of the AC supply and is given by 2πf, where f is the frequency of the supply.

Substituting the given values, we get:

ω = 2π x 50 = 314.16 rad/s

Capacitance = 46,080 / (314.16 x 240^2) = 1.53 x 10^-6 F (farads)

Therefore, the capacitance of the circuit is 1.53 x 10^-6 F.

The mass of air vented out in one day from the bathroom with a volume flow rate of 32 l/s and air density of 1.20 kg/m3 is approximately 3,283.2 kg.

To calculate the mass of air vented out in one day, first, we need to find the volume of air vented out in one day, which is given by:

Volume flow rate x time = 32 l/s x 86,400 s/day = 2,764,800 l/day

Then, we can convert this volume to mass using the density of air:

Mass = Volume x Density = 2,764,800 l/day x 1.20 kg/m3 = 3,283.2 kg/day

Therefore, the mass of air vented out in one day from the bathroom is approximately 3,283.2 kg.
