Sw = (QBv1/(m*sqrt(2*g)*Lw))^(2/3)
This formula uses 1 Functions, 5 Variables
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
Height of Water above Crest of Weir - (Measured in Meter) - Height of Water above Crest of Weir is defined as the water surface height above crest.
Bazins Discharge without Velocity - (Measured in Cubic Meter per Second) - Bazins Discharge without Velocity is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.
Bazins Coefficient - Bazins Coefficient is the constant value obtained by Head.
Acceleration due to Gravity - (Measured in Meter per Square Second) - The Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
Length of Weir Crest - (Measured in Meter) - Length of Weir Crest is the measurement or extent of Weir Crest from end to end.
STEP 1: Convert Input(s) to Base Unit
Bazins Discharge without Velocity: 15.3 Cubic Meter per Second --> 15.3 Cubic Meter per Second No Conversion Required
Bazins Coefficient: 0.407 --> No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Length of Weir Crest: 3 Meter --> 3 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Sw = (QBv1/(m*sqrt(2*g)*Lw))^(2/3) --> (15.3/(0.407*sqrt(2*9.8)*3))^(2/3)
Evaluating ... ...
Sw = 2.00092965507993
STEP 3: Convert Result to Output's Unit
2.00092965507993 Meter --> No Conversion Required
FINAL ANSWER
2.00092965507993 2.00093 Meter <-- Height of Water above Crest of Weir
(Calculation completed in 00.004 seconds)

What does Discharge Mean?

Discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.

What is meant by head?

Head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. The static head of a pump is the maximum height (pressure) it can deliver.
