Maximum Pressure Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Pressure Coefficient = (Total Pressure-Pressure)/(0.5*Density of Material*Freestream Velocity^2)
C_p,max = (P_T-P)/(0.5*ρ*V_∞^2)
This formula uses 5 Variables

Variables Used

Maximum Pressure Coefficient - The Maximum Pressure Coefficient is the maximum value of pressure coefficient.
Total Pressure - (Measured in Pascal) - Total Pressure is the sum of all the forces that the gas molecules exert on the walls of their container.
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 of Material - (Measured in Kilogram per Cubic Meter) - Density of material is ratio of mass of material to its volume.
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

Total Pressure: 120000 Pascal --> 120000 Pascal No Conversion Required
Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Density of Material: 0.11 Kilogram per Cubic Meter --> 0.11 Kilogram per Cubic Meter No Conversion Required
Freestream Velocity: 98 Meter per Second --> 98 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_p,max = (P_T-P)/(0.5*ρ*V_∞^2) --> (120000-800)/(0.5*0.11*98^2)
