Velocity of water at inlet of draft tube given draft tube efficiency Solution

Follow our step by step solution on how to calculate Velocity of water at inlet of draft tube given draft tube efficiency?

FIRST Step Consider the formula

V 1 = \sqrt{\frac{({V 2}^{2}) + (h f \cdot 2 \cdot [g])}{1 - η d}}

Next Step Substitute values of Variables

∴

V 1 = \sqrt{\frac{({1.2m/s}^{2}) + (0.1m \cdot 2 \cdot [g])}{1 - 0.9}}

Next Step Substitute values of Constants

∴

V 1 = \sqrt{\frac{({1.2m/s}^{2}) + (0.1m \cdot 2 \cdot 9.8066m/s²)}{1 - 0.9}}

Next Step Prepare to Evaluate

∴

V 1 = \sqrt{\frac{({1.2}^{2}) + (0.1 \cdot 2 \cdot 9.8066)}{1 - 0.9}}

Next Step Evaluate

∴

V 1 = 5.83209224892748m/s

LAST Step Rounding Answer

∴

V 1 = 5.8321m/s
