Is the exhaust volume delivered by a screw air compressor the volumetric flow rate under the operating pressure, or is it the flow rate at standard conditions?
Thread Content
For example, in the case of a 30HP-22kW air compressor, the exhaust flow rate at 0.8 Mpa is 3.4 m3/min. Is this exhaust flow rate the volumetric flow rate at an outlet pressure of 0.8 Mpa, or is it the volumetric flow rate after conversion to standard cubic meters? I need to calculate the mass flow rate. Should the value of 3.4 be used with the density at 0.8 Mpa, or should the density under standard conditions be used? For example, a very common parameter table like this: L:L
Under normal circumstances, it is the flow rate under standard conditions
Thank you{:2_36:}
Generally, the air volume indicated on the nameplate refers to the flow rate at the compressor’s inlet, which assumes that there is no internal leakage in the compressor
