Mean Velocity of Flow for Total Energy per Unit Weight of Water in Flow Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Constants Used

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

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

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.
Total Energy - (Measured in Joule) - Total Energy is the sum of the kinetic energy and the potential energy of the system under consideration.
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

Total Energy: 8.6 Joule --> 8.6 Joule 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

V_mean = sqrt((E_total-(d_f+y))*2*[g]) --> sqrt((8.6-(3.3+0.04))*2*[g])

Evaluating ... ...
