Pressure Ratio for Unsteady Waves with Subtracted Induced Mass Motion for Expansion Waves Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure Ratio = (1-((Specific Heat Ratio-1)/2)*(Induced Mass Motion/Speed of Sound))^(2*Specific Heat Ratio/(Specific Heat Ratio-1))
r_p = (1-((γ-1)/2)*(u'/c_speed))^(2*γ/(γ-1))
This formula uses 4 Variables

Variables Used

Pressure Ratio - Pressure Ratio is ratio of final to initial pressure.
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.
Induced Mass Motion - (Measured in Kilogram Square Meter) - Induced Mass Motion, added mass or virtual mass is the inertia added to a system because an accelerating or decelerating body must move some volume of surrounding fluid as it moves through it.
Speed of Sound - (Measured in Meter per Second) - The speed of sound is defined as the dynamic propagation of sound waves.

STEP 1: Convert Input(s) to Base Unit

Specific Heat Ratio: 1.6 --> No Conversion Required
Induced Mass Motion: 8.5 Kilogram Square Meter --> 8.5 Kilogram Square Meter No Conversion Required
Speed of Sound: 343 Meter per Second --> 343 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_p = (1-((γ-1)/2)*(u'/c_speed))^(2*γ/(γ-1)) --> (1-((1.6-1)/2)*(8.5/343))^(2*1.6/(1.6-1))

Evaluating ... ...

r_p = 0.960983280745636

STEP 3: Convert Result to Output's Unit

0.960983280745636 --> No Conversion Required

FINAL ANSWER

0.960983280745636 ≈ 0.960983 <-- Pressure Ratio
