Discharge through Small Rectangular Shaped Aperture Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge for Small Rectangular Aperture = Constant for Small Rectangular Aperture*(Height of Water above Crest of Weir-(Height of Small Rectangular Aperture/3))
Q_srw = K_Flow*(S_w-(h_ap/3))
This formula uses 4 Variables

Variables Used

Discharge for Small Rectangular Aperture - (Measured in Cubic Meter per Second) - Discharge for Small Rectangular Aperture is the rate of flow of a liquid.
Constant for Small Rectangular Aperture - Constant for Small Rectangular Aperture is defined by empirical formula given for Small Rectangular Aperture.
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.
Height of Small Rectangular Aperture - (Measured in Meter) - Height of Small Rectangular Aperture is the distance between the lowest and highest points of Small Rectangular Aperture.

STEP 1: Convert Input(s) to Base Unit

Constant for Small Rectangular Aperture: 7.81 --> No Conversion Required
Height of Water above Crest of Weir: 2 Meter --> 2 Meter No Conversion Required
Height of Small Rectangular Aperture: 1.5 Meter --> 1.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_srw = K_Flow*(S_w-(h_ap/3)) --> 7.81*(2-(1.5/3))

Evaluating ... ...

Q_srw = 11.715

STEP 3: Convert Result to Output's Unit

11.715 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

11.715 Cubic Meter per Second <-- Discharge for Small Rectangular Aperture

(Calculation completed in 00.004 seconds)
