At an inlet pressure of 10.0 MPAG, the standard flow rate of the compressor is 100 NM3/H; what is it at an inlet pressure of 5.0 MPAG? All other conditions remain the same?
It depends on the compression ratio of your compressor; it’s difficult to say exactly what it will be. However, when the pressure is reduced to 0.5 MPA, the compression ratio of the compressor increases and the temperature also rises, which may lead to an automatic shutdown
The standard flow rate remains 100 NM3/H. The standard flow rate refers to the flow rate at 1 atmosphere of pressure and 0 degrees Celsius; it is independent of pressure.
For positive-displacement compressors, if you want to convert their standard flow rate into the volumetric flow rate of the intake air, you divide 100 by 101, which gives 0.99. If the same equipment is used and nothing else changes, but the intake pressure increases to 5.0 MPa, then its standard flow rate will be 0.99*5.1 = 50.49 NM3/H. Of course, this is only a theoretical value; as the compression ratio increases, the compression efficiency decreases, and as a result, the volume of exhaust gas produced also decreases. I can’t calculate the exact amount because I don’t know the exhaust pressure here. If needed, you can contact me at 18994937995
