17) For a two stage reciprocating compressor, compression from p1 to p3 is with perfect intercooling and no pressure losses. If compression in both the cylinders follows the same polytropic process and the atmospheric pressu
p2 = p1.p3

mean effective pressure
The ratio of workdone per cycle to the stroke volume of the compressor is known as mean effective pressure.
Correct
less than
Inlet pressure is the absolute pressure of air at the inlet of a compressor. The inlet pressure is always less than the discharge pressure.
Discharge pressure is the absolute pressure of air at the outlet of a compressor.
Compression ratio or Pressure ratio is the ratio of discharge pressure to the inlet pressure. Since the discharge pressure is always more than the inlet pressure, therefore the compression ratio is more than unity.
The compression ratio for the compressor is always greater than unity.
Compression ratio or Pressure ratio is the ratio of discharge pressure to the inlet pressure. Since the discharge pressure is always more than the inlet pressure, therefore the compression ratio is more than unity.
