Hydraulic Loss Coefficient from Suction Pipe Entrance to Pump Solution

Follow our step by step solution on how to calculate Hydraulic Loss Coefficient from Suction Pipe Entrance to Pump?

FIRST Step Consider the formula

f = \frac{((p' + Zs) \cdot \frac{y w}{γ m}) - Zs + Z p}{\frac{{Vs}^{2}}{2} \cdot [g]}

Next Step Substitute values of Variables

∴

f = \frac{((2.1m + 6m) \cdot \frac{9.807kN/m³}{10kN/m³}) - 6m + 6.5m}{\frac{{9m/s}^{2}}{2} \cdot [g]}

Next Step Substitute values of Constants

∴

f = \frac{((2.1m + 6m) \cdot \frac{9.807kN/m³}{10kN/m³}) - 6m + 6.5m}{\frac{{9m/s}^{2}}{2} \cdot 9.8066m/s²}

Next Step Convert Units

∴

f = \frac{((2.1m + 6m) \cdot \frac{9807N/m³}{10000N/m³}) - 6m + 6.5m}{\frac{{9m/s}^{2}}{2} \cdot 9.8066m/s²}

Next Step Prepare to Evaluate

∴

f = \frac{((2.1 + 6) \cdot \frac{9807}{10000}) - 6 + 6.5}{\frac{9^{2}}{2} \cdot 9.8066}

Next Step Evaluate

∴

f = 0.0212596227062601

LAST Step Rounding Answer

∴

f = 0.0213
