Critical Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical Temperature = (2*Stagnation Temperature)/(Specific Heat Ratio+1)
T_cr = (2*T₀)/(γ+1)
This formula uses 3 Variables

Variables Used

Critical Temperature - (Measured in Kelvin) - Critical Temperature is defined as the temperature that will exist at a point when the flow becomes sonic at that point.
Stagnation Temperature - (Measured in Kelvin) - Stagnation Temperature is defined as the temperature that would exist if the flow were slowed down isentropically to zero velocity.
Specific Heat Ratio - The Specific Heat Ratio is the ratio of the heat capacity at constant pressure to heat capacity at constant volume of the flowing fluid for non-viscous and compressible flow.

STEP 1: Convert Input(s) to Base Unit

Stagnation Temperature: 300 Kelvin --> 300 Kelvin No Conversion Required
Specific Heat Ratio: 1.4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_cr = (2*T₀)/(γ+1) --> (2*300)/(1.4+1)

Evaluating ... ...

T_cr = 250

STEP 3: Convert Result to Output's Unit

250 Kelvin --> No Conversion Required

FINAL ANSWER

250 Kelvin <-- Critical Temperature
