- Air Flows Steadily Through An Air Compressor At A Rate Of 0 4 Kg S As Shown In Figure Q4 B The Air Enters The Compres 1 (91.88 KiB) Viewed 64 times
Air flows steadily through an air compressor at a rate of 0.4 kg/s, as shown in Figure Q4(b). The air enters the compressor at 6 m/s with a pressure of 1 bar and a specific volume of 0.85 m3/kg. It leaves at 4.5 m/s with a pressure of 6.9 bar and a specific volume of 0.16 m3/kg. The internal energy of the air leaving the compressor is 88 kJ/kg greater than that of the air entering it. Cooling water absorbs heat from the air at the rate of 59 kW in a jacket surrounding the compressor cylinder. Determine: (i) the power required to drive the compressor; (ii) the inlet cross-section area of the pipe; and (iii) the outlet cross-section area of the pipe.
