Looking to calculate the system resistance curve of a piping system that splits to different processes. The required flow rates and pressures are known at the endpoints. What is the method for determining the system resistance curve at the points shown in the attached sketch?
What is the correct type of pressure (static or total) used in the compressibility factor, KP, when calculating fan power? Howden's Fan Engineering book seems to indicate total pressures should be used, but I also have a PDF from Howden that indicates static pressures should be used. Online...
