A single acting air motor has a bore of 380mm and stroke of 610mm. The supply pressure and temperature is 6.2 bar and 150 oC respectively. The air motor has a speed of 200 rpm, back pressure of 1.03 bar and cut-off ratio of 0.46. The clearance volume is 20% of the swept volume and mechanical efficiency is 95%. The law of compression and expansion can be expressed by pV1.35 = constant. Considering the temperature and pressure of the air in the clearance space at the beginning of admission are 6.2 bar and 150 oC respectively, calculate;

(a) Air consumption

(b) The air temperature after blow down

(d) T0h.8e sha0f.4t power developed.
