The discharge through fully submerged orifice is -
Where,
H = Difference in level of water
H1 = Height of water above the top of the orifice on the upstream side
H2 = Height of water above the bottom of the orifice
1
\({c_d} \times b \times \left( {{H_2} - {H_1}} \right) \times \sqrt {2gH} \)
2
\({c_d} \times b \times \left( {\;H_2^{\frac{3}{2}} - H_1^{\frac{3}{2}}} \right) \times \sqrt {2gH} \)
