Head when End Contractions is suppressed Solution

Follow our step by step solution on how to calculate Head when End Contractions is suppressed?

FIRST Step Consider the formula

H Stillwater = {(\frac{Q Fr'}{1.84 \cdot L w})}^{\frac{2}{3}}

Next Step Substitute values of Variables

∴

H Stillwater = {(\frac{28m³/s}{1.84 \cdot 3m})}^{\frac{2}{3}}

Next Step Prepare to Evaluate

∴

H Stillwater = {(\frac{28}{1.84 \cdot 3})}^{\frac{2}{3}}

Next Step Evaluate

∴

H Stillwater = 2.95220131314881m

LAST Step Rounding Answer

∴

H Stillwater = 2.9522m
