Let A $$=$$ $$cross-section$$ of tanka $$=$$ $$cross-section$$ hole V $$=$$ velocity with which level decreasesv $$=$$ velocity of efflux From equation of continuity $$av=AV$$⇒$$V=avA$$    By using Bernoulli's theorem for energy per unit volume Energy per unit volume at point A                            $$=$$ Energy per unit volume at point $$BP+$$ρ$$gh+12$$ρ$$V2=P+0+12$$ρ$$v2$$⇒$$v2=2gh1$$−$$aA2=2$$×$$10$$×$$(3$$−$$0.525)1$$−$$(0.1)2=50(m/$$$$sec$$$$)2$$
