Speed of Sound Upstream of Sound Wave Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Speed Upstream = sqrt((Specific Heat Ratio-1)*((Flow Velocity Downstream of Sound^2-Flow Velocity Upstream of Sound^2)/2+Sound Speed Downstream^2/(Specific Heat Ratio-1)))
a₁ = sqrt((γ-1)*((u₂^2-u₁^2)/2+a₂^2/(γ-1)))
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Sound Speed Upstream - (Measured in Meter per Second) - Sound Speed Upstream refers to the speed of sound in a medium before passing through a sound wave.
Specific Heat Ratio - The Specific Heat Ratio is the ratio of the heat capacity at constant pressure to heat capacity at constant volume of the flowing fluid for non-viscous and compressible flow.
Flow Velocity Downstream of Sound - (Measured in Meter per Second) - Flow Velocity Downstream of Sound represents the velocity of a fluid flow or airflow after being influenced by a sound wave.
Flow Velocity Upstream of Sound - (Measured in Meter per Second) - Flow Velocity Upstream of Sound represents the velocity of a fluid flow or airflow before being influenced by a sound wave.
Sound Speed Downstream - (Measured in Meter per Second) - Sound Speed Downstream refers to the speed of sound in a medium after passing through a sound wave or disturbance.

STEP 1: Convert Input(s) to Base Unit

Specific Heat Ratio: 1.4 --> No Conversion Required
Flow Velocity Downstream of Sound: 45 Meter per Second --> 45 Meter per Second No Conversion Required
Flow Velocity Upstream of Sound: 80 Meter per Second --> 80 Meter per Second No Conversion Required
Sound Speed Downstream: 31.9 Meter per Second --> 31.9 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a₁ = sqrt((γ-1)*((u₂^2-u₁^2)/2+a₂^2/(γ-1))) --> sqrt((1.4-1)*((45^2-80^2)/2+31.9^2/(1.4-1)))

Evaluating ... ...

a₁ = 11.9419428905015

STEP 3: Convert Result to Output's Unit

11.9419428905015 Meter per Second --> No Conversion Required

FINAL ANSWER

11.9419428905015 ≈ 11.94194 Meter per Second <-- Sound Speed Upstream

On what factors does the speed of sound depends?

The speed of sound in a medium is determined by a combination of the medium's rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound. The greater the density of a medium, the slower the speed of sound.
