203) The discharge through a wholly drowned orifice is given by (where H₁ = Height of water (on the upstream side) above the top of the orifice, H₂ = Height of water (on the downstream side) above the bottom of the orifice, a

204) If the value of coefficient of discharge increases, the discharge through the orifice decreases.
