A 12 x 14 in double-acting air compressor with 5.5% clearance operates at 150 rpm, drawing air at 14.5 psia and 85 ̊F and discharging is at 62 psia, the compression and expansion processes are polytropic with n=1.34. Determine: a) The volume of free air handled per minute, if atmospheric conditions are 82 ̊F and 14.7 psia, b) The heat rejected, c) The indicated work of the compressor if the compression efficiency is 87% d) The ideal work
