Answer is:
mean effective pressure
Explanation:
The ratio of workdone per cycle to the stroke volume of the compressor is known as mean effective pressure.
Answer is:
Correct
Answer is:
less than
Explanation:
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.
