Head available at Base of Nozzle Solution

Follow our step by step solution on how to calculate Head available at Base of Nozzle?

FIRST Step Consider the formula

H bn = H in - (4 \cdot μ \cdot L \cdot \frac{{V f}^{2}}{D \cdot 2 \cdot [g]})

Next Step Substitute values of Variables

∴

H bn = 3193.2m - (4 \cdot 0.01 \cdot 1200m \cdot \frac{{12.5m/s}^{2}}{0.12m \cdot 2 \cdot [g]})

Next Step Substitute values of Constants

∴

H bn = 3193.2m - (4 \cdot 0.01 \cdot 1200m \cdot \frac{{12.5m/s}^{2}}{0.12m \cdot 2 \cdot 9.8066m/s²})

Next Step Prepare to Evaluate

∴

H bn = 3193.2 - (4 \cdot 0.01 \cdot 1200 \cdot \frac{{12.5}^{2}}{0.12 \cdot 2 \cdot 9.8066})

Next Step Evaluate

∴

H bn = 6.58683444397366m

LAST Step Rounding Answer

∴

H bn = 6.5868m
