Total Energy per unit Weight of Water in Flow Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Energy = ((Mean Velocity^2)/(2*[g]))+Depth of Flow+Height above Datum
E_total = ((V_mean^2)/(2*[g]))+d_f+y
This formula uses 1 Constants, 4 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Total Energy - (Measured in Joule) - Total Energy is the sum of the kinetic energy and the potential energy of the system under consideration.
Mean Velocity - (Measured in Meter per Second) - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T.
Depth of Flow - (Measured in Meter) - Depth of Flow is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.
Height above Datum - (Measured in Meter) - Height above datum is the elevation from surface of zero elevation to which heights of various points are referenced.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity: 10.1 Meter per Second --> 10.1 Meter per Second No Conversion Required
Depth of Flow: 3.3 Meter --> 3.3 Meter No Conversion Required
Height above Datum: 40 Millimeter --> 0.04 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_total = ((V_mean^2)/(2*[g]))+d_f+y --> ((10.1^2)/(2*[g]))+3.3+0.04

Evaluating ... ...

E_total = 8.54106254429392

STEP 3: Convert Result to Output's Unit

8.54106254429392 Joule --> No Conversion Required

FINAL ANSWER

8.54106254429392 ≈ 8.541063 Joule <-- Total Energy
