Calculating the orifice diameter on a restrictor application
Calculating the orifice diameter on a restrictor application
(OP)
I'm trying to calculate the orifice diameter for an application where the purpose is to dampen the high pressure spikes of a fuel pump. The pressure pulsations damage a pressure sensor, which requires the dampened lower pressure. The flow rate is 0 because the orifice leads to a blind spot (the sensor itself). The target DP is around 500 psi.
All I have is:
D= 0.23 * sq(Flow rate/sq(dP))
Is there a better equation where the flow rate is not a factor?
Thank you very much.

If you want to also reduce the pressure as seen by the sensor, that is a different problem. This will require flow. Thus the sensor could be "teed" between two orifices. Again using electrical anologe, the area of ofices is used as resitors in a "voltage divider".
