Answer:
The pressure loss in the pipe is 7.792 psig
Explanation:
Given;
flow rate Q = 130 scfm
length of pipeline =170ft
atmospheric pressure = 14.7 psia
pressure in pipe = 105 psig, to psia = 105 + 14.7 = 119.7 psia
Compression ratio (CR) = pressure in pipe/atmospheric pressure
Compression ratio (CR) = 119.7/14.7 = 8.143
Pressure loss in the pipe can be calculated as follows:
[tex]P_L=\frac{0.1025LQ^2}{3600*CR*d^{5.31}}[/tex]
from schedule table, 1-in schedule 40 pipe has a diameter d.
[tex]d^{5.31} = 1.2892[/tex]
Substituting these values, pressure loss in the pipe becomes
[tex]P_L=\frac{0.1025LQ^2}{3600*CR*d^{5.31}} = \frac{0.1025*170*(130)^2}{3600*8.143*1.2892} = 7.792 psig = 22.492 psi[/tex]
Therefore, the pressure loss in the pipe is 7.792 psig
