WebCalculating Valve Pressure Drop. There are a few formulas that can be used to calculate pressure drop but I find it is easier to use calculate pressure drop across a valve by using the following formula: ∆p = 0.5Kρv2. where, ∆p = Pressure drop, Pa. K = Valve K factor. ρ = Density of water, 997 kg/m 3. WebSep 23, 2024 · BTUH = 100 x 40 x 500 = 2,000,000 BTUH. If we look at the chart provided below, we see the correction factor is 0.911.
