I want to make up a spreadsheet that will calculate the friction pressure loss in piping for different gases.
I found the 'Darcy Weisbach' equation but I have a few questions as follows -
Can this equation be used for compressible gases. One source says valid only for incompressible( the other (Piping Calculations Manual - E. sashi Menon) says it is fine for gases?
Secondly - The fluid density and viscosity, can these be specified at atmospheric or at the pipe pressure, if so where is a good source for these values.
