Density before Shock Formation for Compression Wave Solution

STEP 0: Pre-Calculation Summary

Formula Used

Density Behind Shock = Stagnation pressure ahead of shock/(1+((Specific Heat Ratio-1)/2)*(Normal velocity/Old Speed of Sound))^(2*Specific Heat Ratio/(Specific Heat Ratio-Time in Seconds))
ρ₂ = p₀₁/(1+((γ-1)/2)*(Vn/c_old))^(2*γ/(γ-t_sec))
This formula uses 6 Variables

Variables Used

Density Behind Shock - (Measured in Kilogram per Cubic Meter) - Density behind shock is the density of the fluid in the upstream direction of shock.
Stagnation pressure ahead of shock - (Measured in Pascal) - Stagnation pressure ahead of shock is the stagnation or total or pitot pressure before a shockwave has occurred.
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.
Time in Seconds - (Measured in Second) - Time in seconds is what a clock reads, it is a scalar quantity.

STEP 1: Convert Input(s) to Base Unit

Stagnation pressure ahead of shock: 100 Pascal --> 100 Pascal No Conversion Required
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
Time in Seconds: 38 Second --> 38 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ρ₂ = p₀₁/(1+((γ-1)/2)*(Vn/c_old))^(2*γ/(γ-t_sec)) --> 100/(1+((1.6-1)/2)*(1000/342))^(2*1.6/(1.6-38))

Evaluating ... ...

ρ₂ = 105.692638665089

STEP 3: Convert Result to Output's Unit

105.692638665089 Kilogram per Cubic Meter --> No Conversion Required

FINAL ANSWER

105.692638665089 ≈ 105.6926 Kilogram per Cubic Meter <-- Density Behind Shock
