Question

A four-stroke CI engine of 3.0 liter capacity develops indicated power on average of 13.0 kW/m3 of free air induced per minute, while
running at 3600 rpm and having a volumetric efficiency of 72 percent, referred to free air conditions of 1.013 bar and 25°C. A blower
driven mechanically from the engine is proposed to be installed for supercharging. It works through a pressure ratio 1.7 and has an
isentropic efficiency of 80 percent. Assume that at the end of the intake stroke the cylinders contain a volume of charge equal to the
swept volume, at the pressure and temperature of the delivered air from the blower. Taking all mechanical efficiencies to be 80
percent, estimate the air mass flow delivered by the blower in kg/s.
