Central Angle given Wetted Perimeter Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

∠ central = \frac{6.25m \cdot (360 \cdot \frac{π}{180})}{π \cdot 2.64m}

Next Step Substitute values of Constants

∴

∠ central = \frac{6.25m \cdot (360 \cdot \frac{3.1416}{180})}{3.1416 \cdot 2.64m}

Next Step Prepare to Evaluate

∴

∠ central = \frac{6.25 \cdot (360 \cdot \frac{3.1416}{180})}{3.1416 \cdot 2.64}

Next Step Evaluate

∴

∠ central = 4.73484848484848rad
