The following pipeline conveying compressed air is shown in Figure 1. The lengths are: LA= 9,50[m], LB=8,45[m], LC=7,25[m]; LD=7,80[m. There are 2 standard 90 bends: the first one between LA and LB, and the second one between LC and LD. A gate valve is 100% open between LB and LC. The measured flow rate in the network is 90 SCFM and the compressed air temperature is 20.0 [C]. The pressure at is 90 PSIG. The pipe is carbon steel pipe of nominal diameter 1 inch with internal diameter 40.9 [mm] and roughness =0.045 [mm]. The ambient conditions are:
Atmospheric pressure [PSI] = 12,029 PSI Room temperature= 22 C Relative humidity[%] 58
