Velocity Pressure using Wind Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Wind Pressure - (Measured in Pascal) - Wind Pressure is the pressure due to the wind.
Gust Response Factor - The Gust Response Factor is to account for fluctuations in wind speed.
Pressure Coefficient - Pressure Coefficient is the ratio of pressure forces to inertial forces. It is a dimensionless number.

STEP 1: Convert Input(s) to Base Unit

Wind Pressure: 14.88 Poundal per Square Foot --> 22.1438794801375 Pascal (Check conversion here)
Gust Response Factor: 1.2 --> No Conversion Required
Pressure Coefficient: 0.62 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q = p/(G*C_p) --> 22.1438794801375/(1.2*0.62)

Evaluating ... ...

q = 29.7632788711526

STEP 3: Convert Result to Output's Unit

29.7632788711526 Pascal -->20 Poundal per Square Foot (Check conversion here)

FINAL ANSWER

20 Poundal per Square Foot <-- Velocity Pressure
