MHT CET 2024 Physics question
A completely filled water tank of height 'h' has a hole at the bottom. The total pressure at the bottom is 4H and atmospheric pressure is H. The velocity of water flowing out of the hole is ( = density of water)
Answer: (3)
Solution
The total pressure at the bottom (just inside the hole) is ; outside the hole the pressure is atmospheric, . The water at the top surface/inside the tank is practically at rest, so Bernoulli's equation across the hole gives . Hence
