Pressure Coefficient using Wind Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure Coefficient = Wind Pressure/(Velocity Pressure*Gust Response Factor)
C_p = p/(q*G)
This formula uses 4 Variables

Variables Used

Pressure Coefficient - Pressure Coefficient is the ratio of pressure forces to inertial forces. It is a dimensionless number.
Wind Pressure - (Measured in Pascal) - Wind Pressure is the pressure due to the wind.
Velocity Pressure - (Measured in Pascal) - Velocity Pressure is the pressure required to accelerate air from zero velocity to some velocity and is proportional to the kinetic energy of the air stream.
Gust Response Factor - The Gust Response Factor is to account for fluctuations in wind speed.

STEP 1: Convert Input(s) to Base Unit

Wind Pressure: 14.88 Poundal per Square Foot --> 22.1438794801375 Pascal (Check conversion here)
Velocity Pressure: 20 Poundal per Square Foot --> 29.7632788711526 Pascal (Check conversion here)
Gust Response Factor: 1.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_p = p/(q*G) --> 22.1438794801375/(29.7632788711526*1.2)

Evaluating ... ...

C_p = 0.619999999999999

STEP 3: Convert Result to Output's Unit

0.619999999999999 --> No Conversion Required

FINAL ANSWER

0.619999999999999 ≈ 0.62 <-- Pressure Coefficient
