Wall Density of Fluid over Flat Plate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wall Density = Static density/(Wall Temperature/Static Temperature)
ρ_w = ρ_e/(Tw/T_static)
This formula uses 4 Variables

Variables Used

Wall Density - (Measured in Kilogram per Cubic Meter) - Wall Density is the variable considered under turbulent conditions as the density varies near the wall under high viscous flows.
Static density - (Measured in Kilogram per Cubic Meter) - Static density, is the density of the fluid when its not moving, or the density of fluid if we are moving relative to the fluid.
Wall Temperature - (Measured in Kelvin) - Wall Temperature is the temperature at the wall.
Static Temperature - (Measured in Kelvin) - The Static Temperature is defined as the temperature of the gas if it had no ordered motion and was not flowing.

STEP 1: Convert Input(s) to Base Unit

Static density: 100 Kilogram per Cubic Meter --> 100 Kilogram per Cubic Meter No Conversion Required
Wall Temperature: 15 Kelvin --> 15 Kelvin No Conversion Required
Static Temperature: 350 Kelvin --> 350 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ρ_w = ρ_e/(Tw/T_static) --> 100/(15/350)

Evaluating ... ...

ρ_w = 2333.33333333333

STEP 3: Convert Result to Output's Unit

2333.33333333333 Kilogram per Cubic Meter --> No Conversion Required

FINAL ANSWER

2333.33333333333 ≈ 2333.333 Kilogram per Cubic Meter <-- Wall Density
