Flow rate vs pressure drop through an orifice

WebNov 15, 2002 · At the maximum of the pressure drop, dp R0, across the orifice the volume flow rate, Q R0, through the orifice is about 0.29 l/s. That is, 58% of the volume flow rate, Q pump, delivered by the pump goes through the orifice at t=0.78 s. The corresponding Reynolds number is about 63.5×10 3. Hence the flow through the orifice is turbulent at … WebThe pressure drop or flow rate through a valve or orifice plate is typically calculated using the a flow coefficient, Cv or orifice diameter. This article demonstrates how to convert between these two parameters when performing functions such as selecting a valve with an equivalent pressure drop to a given orifice plate.
