For screw compressors, how is the outlet pressure calculated during air testing? It was originally used to compress coke oven gas, with the pressure of the coke oven gas being increased from 0.003 MPa to 0.53 MPa, at a temperature of 40°C and a flow rate of 33,000 Nm3/h. We need to conduct an air test now. What pressure is required to meet the design specifications? Please ask the experts to help answer this; it would be great if there are calculation steps provided
It might be the difference in density between gas and air, along with the inhalation pressure? The differences among ordinary screw compressors are not very significant; can they be ignored? The test run is mainly used to check the mechanical, instrumentation, and electrical aspects; as for changes in flow rate and pressure, they won’t be significant, for reference only. If calculation is to be done, gas should be converted to air, and then equations should be used to determine the conditions at different pressures. The recommended reference book is \"Principles of Chemical Engineering\".
