Discharge over Trapezoidal Notch if overall Coefficient of Discharge for Trapezoidal notch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge by Cipolletti = ((Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*Height of Water above Crest of Weir^(3/2))*((2/3)*Length of Weir Crest+(8/15)*Height of Water above Crest of Weir*tan(Theta/2)))
Q_C = ((C_d*sqrt(2*g)*S_w^(3/2))*((2/3)*L_w+(8/15)*S_w*tan(θ/2)))
This formula uses 2 Functions, 6 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
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

Discharge by Cipolletti - (Measured in Cubic Meter per Second) - Discharge by Cipolletti is the rate of flow of a liquid.
Coefficient of Discharge - The Coefficient of Discharge is ratio of actual discharge to theoretical discharge.
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.
Length of Weir Crest - (Measured in Meter) - Length of Weir Crest is the measurement or extent of Weir Crest from end to end.
Theta - (Measured in Radian) - Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Discharge: 0.66 --> 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
Length of Weir Crest: 3 Meter --> 3 Meter No Conversion Required
Theta: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_C = ((C_d*sqrt(2*g)*S_w^(3/2))*((2/3)*L_w+(8/15)*S_w*tan(θ/2))) --> ((0.66*sqrt(2*9.8)*2^(3/2))*((2/3)*3+(8/15)*2*tan(0.5235987755982/2)))

Evaluating ... ...

Q_C = 18.8911137345802

STEP 3: Convert Result to Output's Unit

18.8911137345802 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

18.8911137345802 ≈ 18.89111 Cubic Meter per Second <-- Discharge by Cipolletti

(Calculation completed in 00.004 seconds)
