Water drains out of a vessel filled with water upto height h through a hole of area A in t seconds.If the height of the water is 4 h then how much time will be required for the water to drain out ?[Assume A lt lt A_(0) (area of tank ) ]

A tank has a hole of area 2 cm^(2) at its bottom and in this hole a conical cork is placed and water is filled up. The water level is made to fall slowly by means of another orifice in the tank. When the water level come to a height of 'H' cm , the conical cork just comes out from the hole. Given, volume of water displaced by the cork =80 cm^(3) , mass of the cork =40 gm , Area of hole =2 cm^(2) , density of water =1 gm//cm^(3) . Area of circular cross-section of conical cork =8cm^(2) , Height of cork submerged in water =(120)/(7) cm . Take g=10m//s^(2) , pi=(22)/(7) and P_(0)=10^(5)N//m^(2) . Calculate the force exerted by water on the curved surface of the conical cork submerged in water when the liquid level in the vessel is equal to H .
