A cyclinderical vessel of cross-sectional area `1000cm^(2)`, fitted with a frictonless piston of mass `10kg`, and filled with water completely. A small hole of cross-sectional area `10mm^(2)` is opened at a point `50cm` deep from the lower surface of the piston. The velocity of efflux from the hole will be

There is a small hole of diameter 2 mm in the wall of a water tank at a depth of 10 m below free water surface. Then the velocity of efflux of water from the hole will be

A long cylindrical tank of cross-sectional area 0.5m^(2) is filled with water. It has a small hole at a height 50cm from the bottom. A movable piston of cross-sectional area almost equal to 0.5m^(2) is fitted on the top of the tank such that it can slide in the tank freely. A load of 20 kg is applied on the top of the water by piston, as shown in the figure. Calculate the speed of the water jet with which it hits the surface when piston is 1m above the bottom. (Ignore the mass of the piston)
