Specific Weight of Water in Suction Pipe Solution

Follow our step by step solution on how to calculate Specific Weight of Water in Suction Pipe?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

y w = \frac{(6m - 6.5m + (0.02 \cdot \frac{{9m/s}^{2}}{2} \cdot [g])) \cdot 10kN/m³}{2.1m + 6m}

Next Step Substitute values of Constants

∴

y w = \frac{(6m - 6.5m + (0.02 \cdot \frac{{9m/s}^{2}}{2} \cdot 9.8066m/s²)) \cdot 10kN/m³}{2.1m + 6m}

Next Step Convert Units

∴

y w = \frac{(6m - 6.5m + (0.02 \cdot \frac{{9m/s}^{2}}{2} \cdot 9.8066m/s²)) \cdot 10000N/m³}{2.1m + 6m}

Next Step Prepare to Evaluate

∴

y w = \frac{(6 - 6.5 + (0.02 \cdot \frac{9^{2}}{2} \cdot 9.8066)) \cdot 10000}{2.1 + 6}

Next Step Evaluate

∴

y w = 9189.36604938272N/m³

Next Step Convert to Output's Unit

∴

y w = 9.18936604938272kN/m³

LAST Step Rounding Answer

∴

y w = 9.1894kN/m³
