New Pressure after Shock Formation, Subtracted to Velocity for Expansion Wave Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure = Density 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))
P = ρ₁*(1-((γ-1)/2)*(Vn/c_old))^(2*γ/(γ-t_sec))
This formula uses 6 Variables

Variables Used

Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Density Ahead of Shock - (Measured in Kilogram per Cubic Meter) - Density ahead of shock is the density of the fluid in the upstream direction of shock.
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

Density Ahead of Shock: 1.4 Kilogram per Cubic Meter --> 1.4 Kilogram per Cubic Meter 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

P = ρ₁*(1-((γ-1)/2)*(Vn/c_old))^(2*γ/(γ-t_sec)) --> 1.4*(1-((1.6-1)/2)*(1000/342))^(2*1.6/(1.6-38))

Evaluating ... ...

P = 1.68343490267119

STEP 3: Convert Result to Output's Unit

1.68343490267119 Pascal --> No Conversion Required

FINAL ANSWER

1.68343490267119 ≈ 1.683435 Pascal <-- Pressure
