3. CO2 is compressed steadily from 80 kPa and 24°C to 1300 kPa and 330°C at a mass flow rate of 0.7 kg/s. The compressor is cooled using fins on the compressor and heat is lost from the compressor at a rate of 20 kW to the surroundings at 24°C. Using constant Cp of 0.978 kJ/kg. K for CO2, determine (a) the power input to the compressor in kW, (b) the isothermal efficiency, and (c) the entropy generation in kW/K.
