Velocity Pressure at given Point as given by ASCE 7 Solution

Follow our step by step solution on how to calculate Velocity Pressure at given Point as given by ASCE 7?

FIRST Step Consider the formula

q i = \frac{(q \cdot G \cdot C ep) - p}{GC pt}

Next Step Substitute values of Variables

∴

q i = \frac{(20pdl/ft² \cdot 1.2 \cdot 0.95) - 14.88pdl/ft²}{0.91}

Next Step Convert Units

∴

q i = \frac{(29.7633Pa \cdot 1.2 \cdot 0.95) - 22.1439Pa}{0.91}

Next Step Prepare to Evaluate

∴

q i = \frac{(29.7633 \cdot 1.2 \cdot 0.95) - 22.1439}{0.91}

Next Step Evaluate

∴

q i = 12.9519323439302Pa

Next Step Convert to Output's Unit

∴

q i = 8.70329670329673pdl/ft²

LAST Step Rounding Answer

∴

q i = 8.7033pdl/ft²
