Q. The discharge through a large rectangular orifice is given by (where H1 = Height of the liquid above the top of the orifice, H2 = Height of the liquid above the bottom of the orifice, b = Breadth of the orifice, and Cd = Coefficient of discharge)

(A) Q = (2/3) Cd × b × (2g) × (H2 - H1)

(B) Q = (2/3) Cd × b × (2g) × (H2 1/2- H1 1/2)

(D) Q = (2/3) Cd × b × (2g) × (H2 2 - H1 2)
