Helium gas (a monatomic gas, constant specific heats) is compressed from 16 psia and 85◦f to 120 psia in a steady-state compressor. the inlet volume flow rate is 8 ft3/s. assume internally reversible process with negligible changes in kinetic and potential energy and ideal gas behavior. determine the power input [hp] and heat transfer rate [btu/s] for each of the following processes (include p − v, t − s diagrams for each): a. isentropic process b. polytropic process with n
