Pressure Drop Units
You would think that all the pipes would have about the same pressure loss per 100 ft for the same nominal pipe size, but not so. The difference is mostly due to differences in actual pipe ID's for the same nominal pipe size for the different types of pipe. For example, CPVC "3/4 inch" pipe has about the same ID as PEX "1 inch" pipe.
