Seeking help to calculate orifice plates
Thread Content
Medium: compressed air; the instantaneous differential pressure across the orifice plate is 4.5 kPa, the flow rate indicated by the integrator is 8000 Nm3/h, and the temperature is 37 degrees Celsius. The inner diameter of the pipe is 309, and the range of the transmitter is 25 kPa. Is it possible to determine the orifice plate opening size? Is it possible to find out what the total amount should be?
Is it to calculate the maximum range of the pressure transmitter, or the orifice diameter, or the maximum flow rate?
There are specialized software programs for orifice plate calculations, and design institutes or manufacturing plants generally have such software. You can also calculate it yourself following the steps in the design manual, but it’s quite troublesome.
