Output power Solution

Follow our step by step solution on how to calculate Output power?

FIRST Step Consider the formula

OP = \frac{w \cdot Q \cdot H m}{1000}

Next Step Substitute values of Variables

∴

OP = \frac{9.81kN/m³ \cdot 0.056m³/s \cdot 25.3m}{1000}

Next Step Convert Units

∴

OP = \frac{9810N/m³ \cdot 0.056m³/s \cdot 25.3m}{1000}

Next Step Prepare to Evaluate

∴

OP = \frac{9810 \cdot 0.056 \cdot 25.3}{1000}

Next Step Evaluate

∴

OP = 13898.808W

Next Step Convert to Output's Unit

∴

OP = 13.898808kW

LAST Step Rounding Answer

∴

OP = 13.8988kW
