Consider a water tank whose cross-sectional area near the top is 0.4 m2. The tank has an opening B near the bottom whose cross-sectional area is 1 cm2. A load of 24 kg is applied on the water surface at the top. When the height of the water level is 40 cm above the bottom, the velocity of water coming out of the opening B is v m/s. The value of v, to the nearest integer, is: [Take g = 10 m/s2]
