engineering recuitment MPPGCL JE 2024 Mock Test Power Engineering Air and Gas Compressors Reciprocating Compressors
A single-stage, reciprocating air compressor is required to compress 1 kg of air from 1 bar to 4 bar. The initial temperature is 27°C. Select the correct option.
(Given, W = Work required for isothermal compression, Wpoly = Work required for polytropic compression (pv1.2 = Constant) and Wisen = Work required for isentropic compression)
1
W > Wpoly > Wisen
2
W < Wisen < Wpoly
3
W < Wpoly < Wisen
4
W > Wisen > Wpoly
