FAQ

What is Critical Density?
The Critical density at a point in a fluid flow is defined as the density that would exist if the flow becomes sonic at that point and is represented as p* =Po*(2/(κ+1))^(1/(κ-1)) or Critical density=Stagnation density *(2/(Specific heat ratio+1))^(1/(Specific heat ratio-1)). Stagnation density is defined as the density of fluid at a stagnation point in a fluid flow and The Specific heat ratio is the ratio of the heat capacity at constant pressure to heat capacity at constant volume.
How to calculate Critical Density?
The Critical density at a point in a fluid flow is defined as the density that would exist if the flow becomes sonic at that point is calculated using Critical density=Stagnation density *(2/(Specific heat ratio+1))^(1/(Specific heat ratio-1)). To calculate Critical Density, you need Stagnation density (Po) and Specific heat ratio (κ).
