Hyjack offers a calculator for the three major mechanical compressors used for hydrogen gas: centrifugal, reciprocating (piston) and diaphragm.
The total power requirement of a compressor for a given duty is the sum of the gas power and the friction power. The gas power is directly proportional to head and mass flow and inversely proportional to efficiency. Mechanical losses in the bearings and, to a lesser extent, in the seals are the primary source of friction power.
