Drawdown at a 0. 20-m diameter well, which has been pumping at a rate of 1,000 m3/day for a long enough time that steady-state conditions have been reached, is determined to be 0. 70 m. The aquifer is 10. 0 m thick. An observation well located 10 m away has been drawn down by 0. 20 m. Determine the hydraulic conductivity of the aquifer
Answer:the aquifer’s hydraulic conductivity is K = 10.039 m/day
transmissivity T = 331.287 m/day
the drawdown 100 m away from the well is s = 1.452 m
Explanation:Given that :
The constant pumps rate Q = 2000 m³/day
R₁ =160 m → H₁ = 249 m
R₂ = 453 m → H₂ = 250 m
The confined aquifer B is 33 m thick
The hydraulic conductivity K =
K =
K =
K = 10.039 m/day
Transmissivity T = K × B
T = 10.039×33
T = 331.287 m/day
TO find the drawdown 100 m away from the well; we have:
K =
H₃ = 248.548 m
Drawdown (s) = H₂ - H₃
s = (250 - 248.548)m

A shaft encoder is mounted on a 50 mm radius tracking wheel to monitor linear displacement. If the encoder produces 400 pulses per revolution. What is the linear displacement in mm per pulse?
The linear displacement in mm per pulse is gotten as; 254.64 mm per pulse
How to Calculate Linear Displacement?Circumference of a circle is;
C = 2πr
We have;
Radius; r = 50 mm = 0.05 m
Thus;
C = 2π * 0.05
C = 0.3142 m
Angular displacement = 0.2/0.3412
Angular displacement = 0.6366
Formula for linear displacement is;
Linear Displacement = angular displacement * number of pulses per revolution
Linear Displacement = 0.6366 × 400

a 230v shunt motor delivers 30hp at the shaft at 1120rpm. if the motor has an efficiency of 87% at this load, determine: the total input power the line current
Shunt motors are direct current motors that have parallel windings with identical voltage. The total input power of the shunt motor is 25.724 kW and the line current will be 111.843 A.
What are input power and line current?Total input power is the ratio of the output power and the efficiency, while the line current is the proportion of input power to an input voltage.
The total input power (total IP) is calculated as:
Given,
Output power (OP) = 30 hp
Efficiency = 0.87
Substituting values:
[tex]\begin{aligned}\text{Total IP} &= \rm \dfrac {OP}{efficiency}\\\\&= \dfrac {30 \times 746 \rm \;watts}{0.87}\\\\&= 25.724 \;\rm kW \end {aligned}[/tex]
Line current is calculated as:
Given,
Input power (IP) = 25.724 kW
Input voltage (IV) = 230 Volt
Solving for line current:
[tex]\begin{aligned} \text{Line current} &= \rm \dfrac{IP}{IV}\\\\&= \dfrac{25.724 \times 10^{3}}{230}\\\\&= 111.843 \;\rm A \end{aligned}[/tex]
Therefore, the total input power of the shunt is 25.724 kW, and the line current is 111.843 A.

The average repair cost of a microwave oven is 55$, with a standard deviation of 8$. the costs are normally distributed. If 12 ovens are repaired, find the probability that the mean of the repair bills will be greater than 60$.
The probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.
What is Probability?The distribution of the sample means for repair costs of 12 microwave ovens can be approximated to a normal distribution, with a mean of the population repair cost, μ = $55 and a standard deviation of the sample mean, σ/√n = $8/√12 ≈ $2.31.
We need to find the probability that the sample mean is greater than $60. Using the formula for z-score:
z = (x - μ) / (σ / √n)
= (60 - 55) / (2.31)
≈ 2.16
We can look up the area under the standard normal distribution curve for z-score 2.16 in a z-table or calculate it using software. The probability is approximately 0.015.
Therefore, the probability that the mean of the repair bills for 12 microwave ovens will be greater than $60 is 0.015 or about 1.5%.
