May I ask the original poster how to calculate the flow rate of a centrifugal pump based on its outlet pressure?
First, a test curve for this pump is required, which is generally available in the relevant data； Next, it is necessary to know the density (or specific gravity) of the medium being transported; this information is usually provided in data sheets. For pure substances such as water, the value can be determined based on temperature. It is also required to record the inlet pressure P_in in MpaG and the outlet pressure P_out in MpaG. The pressure difference is given by P_in – P_out. By multiplying this pressure difference by 102 and dividing by the specific gravity of the medium, the actual head of the pump can be calculated in meters (with all pressure values expressed in MpaG). Finally, the value is determined using the readings from the test curve Of course, you can also look it up in a table~
