Length given Bazins Formula for Discharge if Velocity is not considered Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Weir Crest = Bazins Discharge without Velocity/(Bazins Coefficient*sqrt(2*Acceleration due to Gravity)*Height of Water above Crest of Weir^(3/2))
L_w = Q_Bv1/(m*sqrt(2*g)*S_w^(3/2))
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

Length of Weir Crest - (Measured in Meter) - Length of Weir Crest is the measurement or extent of Weir Crest from end to end.
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.
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.

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
Height of Water above Crest of Weir: 2 Meter --> 2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_w = Q_Bv1/(m*sqrt(2*g)*S_w^(3/2)) --> 15.3/(0.407*sqrt(2*9.8)*2^(3/2))

Evaluating ... ...

L_w = 3.00209196698375

STEP 3: Convert Result to Output's Unit

3.00209196698375 Meter --> No Conversion Required

FINAL ANSWER

3.00209196698375 ≈ 3.002092 Meter <-- Length of Weir Crest
