Head when Coefficient Discharge is Constant Solution

Follow our step by step solution on how to calculate Head when Coefficient Discharge is Constant?

FIRST Step Consider the formula

S w = {(\frac{Q tri}{1.418})}^{\frac{2}{5}}

Next Step Substitute values of Variables

∴

S w = {(\frac{10m³/s}{1.418})}^{\frac{2}{5}}

Next Step Prepare to Evaluate

∴

S w = {(\frac{10}{1.418})}^{\frac{2}{5}}

Next Step Evaluate

∴

S w = 2.18438661984344m

LAST Step Rounding Answer

∴

S w = 2.1844m
