Can the differential pressure calculated using an orifice plate be higher than the pressure inside the pipe?
Thread Content
I encountered some issues in my design and hope that experts can provide answers. Thank you. The pressure in the pipeline where the orifice plate is located is 1 kPa; the calculated maximum differential pressure is 25 kPa, with a maximum pressure loss of 14.6 kPa. Are these calculation results correct? Can the maximum pressure loss be higher than the pressure inside the pipe?
Could it be that an error occurred due to inconsistent units for the parameters used in the calculation?
The calculation results should be wrong, but in practical terms, is your pipeline pressure really only 1 KPa?
The calculation is incorrect; with a pipeline pressure of 1 KPA, how can a differential pressure of 25 KPA be generated? What, the pipeline pressure is only 1 KPA? It seems there’s some problem here
Using an orifice plate for a pipeline under 1 kPa pressure isn’t appropriate, right?
Is the pipeline pressure of 1 KPa incorrect? What is the normal flow rate at such a pressure? Using an orifice plate is not appropriate.
