Height of Aperture given Discharge through Small Rectangular Shaped Aperture Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Discharge for Small Rectangular Aperture: 1.6 Cubic Meter per Second --> 1.6 Cubic Meter per Second No Conversion Required
Constant for Small Rectangular Aperture: 7.81 --> 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

h_ap = -((Q_srw/K_Flow)-S_w)*3 --> -((1.6/7.81)-2)*3

Evaluating ... ...

h_ap = 5.3854033290653

STEP 3: Convert Result to Output's Unit

5.3854033290653 Meter --> No Conversion Required

FINAL ANSWER

5.3854033290653 ≈ 5.385403 Meter <-- Height of Small Rectangular Aperture

What does discharge mean?

The Discharge Through the Small Rectangular Shaped Aperture weir is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.

What is a rectangular weir?

A sharp crested, rectangular weir is simply a flat plate obstruction in an open channel flow path, with a straight, level opening to allow water flow over the weir, as shown in the pictures and diagrams in the rest of this article. It is used to meter flow of water over the weir (and through the open channel) by measuring the head of water over the weir crest.
Uses:
* Able to measure higher flows than v-notch weirs.
* Discharge equation more complex than most other weir types.
* Widely used to measure high flow rates in channels suited to weirs.
