Apr 09, 2015· HP or kW = power Flow Calculations Most common compressor flow conditions are often expressed in: 1. Weight flow-lb/min, lb/h (kg/min. kg/h) 2. SCFM-60°F. 14.7 psia and dry 3. number of mols/h None of these flows can be used directly in calculating compressor performance. All must be converted to ACFM-actual cubic feet per minute.
The power required to drive a reciprocating compressor can be divided into three pieces, adiabatic, valve loss and friction and each will be discussed separately. The power required to compress a volume of gas is represented by the area enclosed by the P-V diagram, or:

Jun 01, 2015· 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.
