Non-Dimensional Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Non Dimensionalized Pressure = Pressure/(Density*Freestream Velocity^2)
p_- = P/(ρ*V_∞^2)
This formula uses 4 Variables

Variables Used

Non Dimensionalized Pressure - Non Dimensionalized Pressure is the technique which can ease the analysis of the problem at hand and reduce the number of free parameters.
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 - (Measured in Kilogram per Cubic Meter) - The Density of a material shows the denseness of that material in a specific given area, this is taken as mass per unit volume of a given object.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air.

STEP 1: Convert Input(s) to Base Unit

Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Density: 663.1 Kilogram per Cubic Meter --> 663.1 Kilogram per Cubic Meter No Conversion Required
Freestream Velocity: 1.228 Meter per Second --> 1.228 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_- = P/(ρ*V_∞^2) --> 800/(663.1*1.228^2)

Evaluating ... ...

p_- = 0.800044650171908

STEP 3: Convert Result to Output's Unit

0.800044650171908 --> No Conversion Required

FINAL ANSWER

0.800044650171908 ≈ 0.800045 <-- Non Dimensionalized Pressure
