Topographic Factor given Velocity Pressure Solution

Follow our step by step solution on how to calculate Topographic Factor given Velocity Pressure?

FIRST Step Consider the formula

K zt = \frac{q}{0.00256 \cdot K z \cdot I \cdot K d \cdot {V B}^{2}}

Next Step Substitute values of Variables

∴

K zt = \frac{20pdl/ft²}{0.00256 \cdot 0.85 \cdot 0.8 \cdot 0.78 \cdot {29.6107m/s}^{2}}

Next Step Convert Units

∴

K zt = \frac{29.7633Pa}{0.00256 \cdot 0.85 \cdot 0.8 \cdot 0.78 \cdot {29.6107m/s}^{2}}

Next Step Prepare to Evaluate

∴

K zt = \frac{29.7633}{0.00256 \cdot 0.85 \cdot 0.8 \cdot 0.78 \cdot {29.6107}^{2}}

Next Step Evaluate

∴

K zt = 24.9999962939714

LAST Step Rounding Answer

∴

K zt = 25
