R22 Pressure Drop
R22 Pressure Drop
(OP)
Anyone, need answer fast.
Pls calculate the pressure drop across a 5/8 od copper tube with wall thickness 0.7mm, length=15m, with R22 hot gas at 70 degC, 20 bar, flow at a) 1hp b) 1.5hp TQ.

RE: R22 Pressure Drop
Using a line sizing program I've written, I get a pressure drop of 0.56 psi for the 1 hp application, and 1.2 psi for the 1.5 hp application. Vapor velocities work out to 551 and 827 ft/min respectively.
