2.3 A two stages, single acting air compressor compresses air to 20bar. The air enters the L.P cylinder at 1bar and 27°c and leaves it at 4.7bar. The air enters the H.P. cylinder at 4.5bar and 27°c. the size of the L.P cylinder is 400mm diameter and 500mm stroke. The clearance volume in both cylinder is 4% of the respective stroke volume. The compressor runs at 200rpm, taking index of compression and expansion in the two cylinders as 1.3. Determine 2.3.1 the indicated power required to run the compressor.

Temperature was rising during the process from 12C to 90C. The inlet volumetric flow rate is 1 m3/min and inlet diameter is 0.03m. At the exit the diameter is the same. Heat flow to the surroundings can be neglected. Determine: a.Mass flow rate [kg/s]   SHOW AND EXPLAIN ALL STEPS PLEASE thanks
