Question

A large tank is partially filled with water. The tank has a small orifice at the bottom and water is coming out of the orifice. When height of water above the orifice is $$2$$ m, rate of flow of water through the orifice is $$0.5$$  $$m3/s$$. when height of water above the orifice is $$0.5$$ m rate of flow of water through the orifice will be

$$(3)Rate$$ of flow through the orifice Q  α   h∴    Q'Q $$=$$ h'h  ⇒   $$Q0.5=$$  $$0.52$$ $$=12$$∴    Q' $$=Q2=0.52$$ $$=0.25$$  $$m3/s$$.
