How to Calculate Critical Pressure?
Critical Pressure calculator uses Critical Pressure = ((2/(Specific Heat Ratio+1))^(Specific Heat Ratio/(Specific Heat Ratio-1)))*(Stagnation Pressure at a point in fluid flow) to calculate the Critical Pressure, The Critical Pressure at a point in a fluid flow is defined as the pressure that would exist if the flow becomes sonic at that point. Critical Pressure is denoted by p_{*} symbol.
How to calculate Critical Pressure using this online calculator? To use this online calculator for Critical Pressure, enter Specific Heat Ratio (γ) & Stagnation Pressure at a point in fluid flow (P_{0}) and hit the calculate button. Here is how the Critical Pressure calculation can be explained with given input values -> 2.90555 = ((2/(1.4+1))^(1.4/(1.4-1)))*(539365.75).
