## Length of the Crest when Discharge Over the Weir(Q) is given Solution

STEP 0: Pre-Calculation Summary
Formula Used
length = (Discharge*3)/(2*coefficient of Discharge rectangular*sqrt(2*Acceleration Due To Gravity)*Head^(3/2))
l = (Q*3)/(2*C d1*sqrt(2*g)*H^(3/2))
This formula uses 1 Functions, 4 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Discharge - Discharge is the rate of flow of a liquid (Measured in Meter³ per Second)
coefficient of discharge rectangular- The coefficient of discharge rectangular portion is considered in discharge through the trapezoidal notch.
Acceleration Due To Gravity - The Acceleration Due To Gravity is acceleration gained by an object because of gravitational force. (Measured in Meter per Square Second)
Head - Head is defined as the height of water columns (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Discharge: 1 Meter³ per Second --> 1 Meter³ per Second No Conversion Required
coefficient of discharge rectangular: 0.63 --> No Conversion Required
Acceleration Due To Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Head: 1 Meter --> 1 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
l = (Q*3)/(2*C d1*sqrt(2*g)*H^(3/2)) --> (1*3)/(2*0.63*sqrt(2*9.8)*1^(3/2))
Evaluating ... ...
l = 0.537802323157888
STEP 3: Convert Result to Output's Unit
0.537802323157888 Meter --> No Conversion Required
0.537802323157888 Meter <-- Length
