Total Energy per unit Weight of Water in Flow Section considering Bed Slope as Datum Solution

Follow our step by step solution on how to calculate Total Energy per unit Weight of Water in Flow Section considering Bed Slope as Datum?

FIRST Step Consider the formula

E total = (\frac{{V FN}^{2}}{2 \cdot [g]}) + d f

Next Step Substitute values of Variables

∴

E total = (\frac{{70m/s}^{2}}{2 \cdot [g]}) + 3.3m

Next Step Substitute values of Constants

∴

E total = (\frac{{70m/s}^{2}}{2 \cdot 9.8066m/s²}) + 3.3m

Next Step Prepare to Evaluate

∴

E total = (\frac{70^{2}}{2 \cdot 9.8066}) + 3.3

Next Step Evaluate

∴

E total = 253.130472179592J

LAST Step Rounding Answer

∴

E total = 253.1305J
