Go Discharge over Weir without considering Velocity

Q Fr' = (\frac{2}{3}) \cdot C d \cdot \sqrt{2 \cdot g} \cdot L w \cdot {S w}^{\frac{3}{2}}

Go Discharge Passing over Weir considering Velocity

Q Fr' = (\frac{2}{3}) \cdot C d \cdot \sqrt{2 \cdot g} \cdot L w \cdot ({(S w + H V)}^{\frac{3}{2}} - {H V}^{\frac{3}{2}})

Go Discharge considering Approach Velocity

Q Fr = (\frac{2}{3}) \cdot C d \cdot \sqrt{2 \cdot g} \cdot (L w - 0.1 \cdot n \cdot H Stillwater) \cdot ({H Stillwater}^{\frac{3}{2}} - {H V}^{\frac{3}{2}})

Go Discharge for Notch which is to be Calibrated

Q Fr' = k Flow \cdot {S w}^{n}
