Loss of head at exit of pipe Solution

Follow our step by step solution on how to calculate Loss of head at exit of pipe?

FIRST Step Consider the formula

h o = \frac{{V f}^{2}}{2 \cdot [g]}

Next Step Substitute values of Variables

∴

h o = \frac{{12.5m/s}^{2}}{2 \cdot [g]}

Next Step Substitute values of Constants

∴

h o = \frac{{12.5m/s}^{2}}{2 \cdot 9.8066m/s²}

Next Step Prepare to Evaluate

∴

h o = \frac{{12.5}^{2}}{2 \cdot 9.8066}

Next Step Evaluate

∴

h o = 7.96653291389006m

LAST Step Rounding Answer

∴

h o = 7.9665m
