1.	An orifice of diameter 8 mm is made on one side of a tank in which water level is 10 mm above the orifice. What is the rate of discharge of water through the orifice?
Answer» SOLUTION :` v= sqrt(2gh )= sqrt(2xx 9.8 xx 10 ) = 14m s^(-1),` Rate of DISCHARGE =AV `= pi (4 xx 10 ^(-3))^(2)xx 14 = 7.03 xx 10 ^(-4) m^(3) s^(-1)`
