Wetted Perimeter given Central Angle Solution

Follow our step by step solution on how to calculate Wetted Perimeter given Central Angle?

FIRST Step Consider the formula

P w = \frac{π \cdot D pipe \cdot ∠ central}{360 \cdot \frac{π}{180}}

Next Step Substitute values of Variables

∴

P w = \frac{π \cdot 2.64m \cdot 120°}{360 \cdot \frac{π}{180}}

Next Step Substitute values of Constants

∴

P w = \frac{3.1416 \cdot 2.64m \cdot 120°}{360 \cdot \frac{3.1416}{180}}

Next Step Convert Units

∴

P w = \frac{3.1416 \cdot 2.64m \cdot 2.0944rad}{360 \cdot \frac{3.1416}{180}}

Next Step Prepare to Evaluate

∴

P w = \frac{3.1416 \cdot 2.64 \cdot 2.0944}{360 \cdot \frac{3.1416}{180}}

Next Step Evaluate

∴

P w = 2.7646015351585m

LAST Step Rounding Answer

∴

P w = 2.7646m
