Problem 3 Part a P=57 Moist air enters the cooler of an air conditioning unit at 25 °C and a relative humidity of 70%. The cooled and dehumidified air leaves the cooler saturated at 18 °C. The temperature of condensed water is 18 °C. The pressure is constant at 101.325 kPa. The mass flow rate of the dry air is mda=67 kg/s. Use the psychometric chart to determine a) The humidity ratio at the...

Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...
