Answer:
There are 2 expected readings greater than 2.70 V
Solution:
As per the question:
Total no. of readings, n = 60 V
Mean of the voltage,
standard deviation,
Now, to find the no. of readings greater than 2.70 V, we find:
The probability of the readings less than 2.70 V, :
Now, from the Probability table of standard normal distribution:
Now,
Now, for the expected no. of readings greater than 2.70 V:
No. of readings expected to be greater than 2.70 V =
No. of readings expected to be greater than 2.70 V = ≈ 2
Answer
diameter of parking lot = 18 in
flowrate = 10 ft³/s
pressure drop = 100 ft
using general equation
taking f = 0.0185
at Z₁ = Z₂
ΔP = 0.266 psi
b) when flow is uphill z₂-z₁ = 2
c) When flow is downhill z₂-z₁ = -2
