FAQ

What is Temperature Ratios?

Temperature Ratios formula is defined as a measure of the ratio of total pressure to total density across an oblique shock wave, providing a critical parameter in understanding the behavior of compressible flows and shock waves in aerodynamics and aerospace engineering and is represented as T_ratio = r_p/ρ_ratio or Temperature Ratio = Pressure Ratio/Density Ratio. Pressure Ratio is ratio of final to initial pressure & Density Ratio higher is also one of the definitions of hypersonic flow. Density ratio across normal shock would reach 6 for calorically perfect gas (air or diatomic gas) at very high Mach numbers.

How to calculate Temperature Ratios?

Temperature Ratios formula is defined as a measure of the ratio of total pressure to total density across an oblique shock wave, providing a critical parameter in understanding the behavior of compressible flows and shock waves in aerodynamics and aerospace engineering is calculated using Temperature Ratio = Pressure Ratio/Density Ratio. To calculate Temperature Ratios, you need Pressure Ratio (r_p) & Density Ratio (ρ_ratio). With our tool, you need to enter the respective value for Pressure Ratio & Density Ratio and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Temperature Ratio?

In this formula, Temperature Ratio uses Pressure Ratio & Density Ratio. We can use 1 other way(s) to calculate the same, which is/are as follows -

Temperature Ratio = (2*Specific Heat Ratio*(Specific Heat Ratio-1))/(Specific Heat Ratio+1)^2*(Mach Number*sin(Wave Angle))^2
