Compressible Area Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area Ratio = ((Specific Heat Ratio+1)/2)^(-(Specific Heat Ratio+1)/(2*Specific Heat Ratio-2))*((1+(Specific Heat Ratio-1)/2*Mach Number^2)^((Specific Heat Ratio+1)/(2*Specific Heat Ratio-2)))/Mach Number
A_r = ((γ+1)/2)^(-(γ+1)/(2*γ-2))*((1+(γ-1)/2*M^2)^((γ+1)/(2*γ-2)))/M
This formula uses 3 Variables

Variables Used

Area Ratio - Area Ratio is defined as the Area ratio of the exit area to that of the throat area.
Specific Heat Ratio - The specific heat ratio describes the ratio of specific heats of a gas at constant pressure to that at constant volume.
Mach Number - Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.

STEP 1: Convert Input(s) to Base Unit

Specific Heat Ratio: 1.33 --> No Conversion Required
Mach Number: 1.4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_r = ((γ+1)/2)^(-(γ+1)/(2*γ-2))*((1+(γ-1)/2*M^2)^((γ+1)/(2*γ-2)))/M --> ((1.33+1)/2)^(-(1.33+1)/(2*1.33-2))*((1+(1.33-1)/2*1.4^2)^((1.33+1)/(2*1.33-2)))/1.4

Evaluating ... ...

A_r = 1.12028343696668

STEP 3: Convert Result to Output's Unit

1.12028343696668 --> No Conversion Required

FINAL ANSWER

1.12028343696668 ≈ 1.120283 <-- Area Ratio

What does Compressible Area Ratio of a rocket nozzle signify?

The area ratio of the exit area to that of the throat area is called as the Compressible Area Ratio.

Throat of the nozzle

The optimum mass flow rate through the system happens when the flow is constricted at the smallest area. For example, a nozzle that can change its area is useful to maximize the mass flow rate. Such type of region where maximum mass flow rate occurs is called as the throat of the nozzle.

How to Calculate Compressible Area Ratio?

Compressible Area Ratio calculator uses Area Ratio = ((Specific Heat Ratio+1)/2)^(-(Specific Heat Ratio+1)/(2*Specific Heat Ratio-2))*((1+(Specific Heat Ratio-1)/2*Mach Number^2)^((Specific Heat Ratio+1)/(2*Specific Heat Ratio-2)))/Mach Number to calculate the Area Ratio, The Compressible Area Ratio can be defined as the Area ratio of the exit area to that of the throat area. The value to be computed depends on the specific heat ratio and Mach number. Area Ratio is denoted by A_r symbol.

How to calculate Compressible Area Ratio using this online calculator? To use this online calculator for Compressible Area Ratio, enter Specific Heat Ratio (γ) & Mach Number (M) and hit the calculate button.
