Discharge through fully sub-merged orifice Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge through Orifice = Coefficient of Discharge*Width*(Height of Liquid Bottom Edge-Height of Liquid Top Edge)*(sqrt(2*9.81*Difference in Liquid Level))
Q_O = C_d*w*(H_b-H_top)*(sqrt(2*9.81*H_L))
This formula uses 1 Functions, 6 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

Discharge through Orifice - (Measured in Cubic Meter per Second) - The Discharge through orifice is an opening, of any size or shape, in a pipe or at the bottom or side wall of a container (water tank, reservoir, etc.), through which fluid is discharged.
Coefficient of Discharge - The Coefficient of Discharge or efflux coefficient is the ratio of the actual discharge to the theoretical discharge.
Width - (Measured in Meter) - Width is the measurement or extent of something from side to side.
Height of Liquid Bottom Edge - (Measured in Meter) - Height of liquid bottom edge is a variable in discharge through the large rectangular orifice.
Height of Liquid Top Edge - (Measured in Meter) - Height of liquid top edge is a variable in discharge through the large rectangular orifice.
Difference in Liquid Level - (Measured in Meter) - The Difference in liquid level is a variable in discharge through the fully submerged orifice.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Discharge: 0.87 --> No Conversion Required
Width: 3.5 Meter --> 3.5 Meter No Conversion Required
Height of Liquid Bottom Edge: 20 Meter --> 20 Meter No Conversion Required
Height of Liquid Top Edge: 19.9 Meter --> 19.9 Meter No Conversion Required
Difference in Liquid Level: 200 Meter --> 200 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_O = C_d*w*(H_b-H_top)*(sqrt(2*9.81*H_L)) --> 0.87*3.5*(20-19.9)*(sqrt(2*9.81*200))

Evaluating ... ...

Q_O = 19.0744399917798

STEP 3: Convert Result to Output's Unit

19.0744399917798 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

19.0744399917798 ≈ 19.07444 Cubic Meter per Second <-- Discharge through Orifice

What is coefficient of discharge?

The co-efficient of discharge is defined as the ratio of the actual discharge from an orifice to the theoretical discharge from the orifice.

What is an orifice?

The orifice is defined as the small opening on the side or bottom of a tank through which any kind of fluid is flowing. The opening can be circular, triangular, or rectangular in cross-section and they are named on the basis of shape accordingly.
