0.4 A condenser works under a vacuum of 700mmHg while air leaks into It at a 4.25kg/hr. The air pump extraction spout has a temperature of 32.9°C and the barometer reading is 760mmHg. Taker for air 0.287kJ/kgK and calculate: 6.4.1 the volume of air removed per hour 6.4.2 the mass of vapour present in the air per hour

A single-stage single acting air compressor takes air in at 1 bar & delivers at 7.5 bar. Work done by the compressor is 38 kJ and the compressor runs at 150 rpm. Calculate the power required in kW/?     the power required in kW?

Compute for the discharge pressure in bar of a single-acting air compressor if the piston-arrangement has a clearance of 7.5% and a volumetric efficiency of 75%. The isentropic compression has an intake pressure of 750 mmHg a. 4.46b. 5.57c. 6.68d. 7.79
