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*Cp)
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*Cp) --> 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
(Calculation completed in 00.004 seconds)
