Calculation of air compressor air volume
Thread Content
I would like to ask my friends: does the exhaust pressure of an air compressor refer to absolute pressure or gauge pressure? Additionally, ignoring temperature changes, for an air compressor with an exhaust pressure of 0.8 Mpa and an exhaust volume of 20 m3 per minute, what is the volume of air per minute at that exhaust pressure?
1. The gauge reading represents gauge pressure, but absolute pressure is required for calculations. Gauge pressure of 0.8 MPa means absolute pressure of 0.9 MPa. 2. The flow rates indicated are nominal values; the conveying (suction) capacity of the fan is in cubic meters under atmospheric temperature conditions. Assume 20 is the standard value, which means 20/9 ； Assume that your flow rate at an atmospheric temperature of 20 is given by (20/9) * (t_out/t_in).
The displacement should have little to do with the exhaust pressure; it’s probably related to the load carried by the machine
