STEP 1: Convert Input(s) to Base Unit

Thickness of Dam: 3.88 Meter --> 3.88 Meter No Conversion Required
Head of Water above Sill of Notch: 2.6457 Meter --> 2.6457 Meter No Conversion Required
Head: 2.55 Meter --> 2.55 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_f = 0.62*b*H*2/3*sqrt(2*[g]*H_w) --> 0.62*3.88*2.6457*2/3*sqrt(2*[g]*2.55)

Evaluating ... ...

V_f = 30.0066960528816

STEP 3: Convert Result to Output's Unit

30.0066960528816 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

30.0066960528816 ≈ 30.0067 Cubic Meter per Second <-- Volumetric Flow Rate

What is rectangular notch?

It may be defined as an opening in the side of a tank or vessel such as liquid surface in the tank is below the level of opening. ... The edges of the notch are bevelled on the downstream side so as to have a sharp-edged sides and crest resulting in minimum contact with the flowing fluid.

What is standard volumetric flow?

Standard volumetric flow rates denote volumetric flow rates of gas corrected to standardised properties of temperature, pressure and relative humidity. Its use is common across engineering and allows a direct comparison to be made between gaseous flows in a manner identical to comparing their mass flow rates.
