Mean Velocity of Flow given Head Loss over Length of Pipe Solution

Follow our step by step solution on how to calculate Mean Velocity of Flow given Head Loss over Length of Pipe?

FIRST Step Consider the formula

V mean = \frac{h}{\frac{32 \cdot μ \cdot L p}{γ f \cdot {D pipe}^{2}}}

Next Step Substitute values of Variables

∴

V mean = \frac{2.5m}{\frac{32 \cdot 10.2P \cdot 0.1m}{9.81kN/m³ \cdot {1.01m}^{2}}}

Next Step Convert Units

∴

V mean = \frac{2.5m}{\frac{32 \cdot 1.02Pa*s \cdot 0.1m}{9810N/m³ \cdot {1.01m}^{2}}}

Next Step Prepare to Evaluate

∴

V mean = \frac{2.5}{\frac{32 \cdot 1.02 \cdot 0.1}{9810 \cdot {1.01}^{2}}}

Next Step Evaluate

∴

V mean = 7664.81387867647m/s

LAST Step Rounding Answer

∴

V mean = 7664.8139m/s
