WebJul 20, 2009 · If P = 9 kg/cm2 is designed pressure, then flow is calculated according to the following formula: Q = k *sqrt (Deltap). In your particular case: DeltaP = 1000 mmH2O = 9806.65 Pa and Q = 5 t/h. This will lead to k = 0.0505. Now, if absoulte pressure is lower, you need to make correction according to the following (approximate) formula: Q = k ...
