Supercharging of an engine is used to increase the inlet airdensity so that more fuel can be added, the result of
which is an increased power output. Assume that ambient air, 100kPa and 27°C, enters the supercharger at a rate
of 250 L/s. The supercharger (compressor) has an isentropicefficiency of 75%, and uses 20 kW of power input.
Assume that the ideal and actual compressor have the same exitpressure. Find the ideal specific work and verify
that the exit pressure is 175 kPa. Find the percent increase inair density entering the engine due to the
supercharger and the entropy generation
