Entrance Loss Coefficient using formula for Head on Entrance measured from Bottom of Culvert Solution

Follow our step by step solution on how to calculate Entrance Loss Coefficient using formula for Head on Entrance measured from Bottom of Culvert?

FIRST Step Consider the formula

K e = (\frac{H in - h}{v m \cdot \frac{v m}{2 \cdot [g]}}) - 1

Next Step Substitute values of Variables

∴

K e = (\frac{10.647m - 1.2m}{10m/s \cdot \frac{10m/s}{2 \cdot [g]}}) - 1

Next Step Substitute values of Constants

∴

K e = (\frac{10.647m - 1.2m}{10m/s \cdot \frac{10m/s}{2 \cdot 9.8066m/s²}}) - 1

Next Step Prepare to Evaluate

∴

K e = (\frac{10.647 - 1.2}{10 \cdot \frac{10}{2 \cdot 9.8066}}) - 1

Next Step Evaluate

∴

K e = 0.852868451

LAST Step Rounding Answer

∴

K e = 0.8529
