How to Calculate Exact pressure ratio?
Exact pressure ratio calculator uses pressure ratio=1+(2*Specific Heat Ratio/(Specific Heat Ratio+1))*(((Mach Number*sin(Wave angle))^2)-1) to calculate the pressure ratio, The Exact pressure ratio formula is defined as product of specific heat ratio and the mach number of the flow before impact at an angle. pressure ratio and is denoted by Rp symbol.
How to calculate Exact pressure ratio using this online calculator? To use this online calculator for Exact pressure ratio, enter Specific Heat Ratio (γ), Mach Number (M) and Wave angle (β) and hit the calculate button. Here is how the Exact pressure ratio calculation can be explained with given input values -> -0.193657 = 1+(2*1.6/(1.6+1))*(((1*sin(10))^2)-1).
