Ratio of New and Old Temperature for Expansion Waves Solution

STEP 0: Pre-Calculation Summary

Formula Used

Temperature Ratio across Shock = (1-((Specific Heat Ratio-1)/2)*(Normal velocity/Old Speed of Sound))^(2)
Tshock_ratio = (1-((γ-1)/2)*(Vn/c_old))^(2)
This formula uses 4 Variables

Variables Used

Temperature Ratio across Shock - Temperature ratio across shock is the ratio of downstream temperature to upstream temperature across the shock wave.
Specific Heat Ratio - The Specific heat ratio of a gas is the ratio of the specific heat of the gas at a constant pressure to its specific heat at a constant volume.
Normal velocity - (Measured in Meter per Second) - Normal velocity is the velocity normal to the shock formation.
Old Speed of Sound - (Measured in Meter per Second) - Old speed of sound is the speed of sound before the shock.

STEP 1: Convert Input(s) to Base Unit

Specific Heat Ratio: 1.6 --> No Conversion Required
Normal velocity: 1000 Meter per Second --> 1000 Meter per Second No Conversion Required
Old Speed of Sound: 342 Meter per Second --> 342 Meter per Second No Conversion Required
