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

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 Correct Answer <span class="math-tex">\({c_d} \times b \times \left( {{H_2} - {H_1}} \right) \times \sqrt {2gH} \)</span>

Explanation:

Important Points

Height of water above the centre of orifice on upstream side

= H1 + (H2- H1)/2

= (H1+ H2)/2 

Height of water above the centre of orifice on downstream side

= (H1+ H2)/2 – H
