A tube is attached as shown in closed vessel containing water. The velocity of water coming out from a small hole is :

In a container, filled with water upto a height h, a hole is made in the bottom. The velocity of water flowing out of the hole is

In a container having water filled upto a height h, a hole is made in the bottom. The velocity of the water flowing out of the hole is

Water and mercury are filled in two cylindrical vessels up to same height. Both vessels have a hole in the wall near the bottom. The velocity of water and mercury coming out of the holes are v_1 and v_2 respectively. Then

Water and mercury are filled in two cylindrical vessels up to same height. Both vessels have a hole in the wall near the bottom. The velocity of water and mercury coming out of the holes are v_1 and v_2 respectively. Then

Water and mercury are filled in towi cylinderical vessels up to same height. Both vesels hve a hole in thewal near the bottom. The velocity of water and mercury coming out of the holes are v_1 and v_2 respectively.

A large tank containing water has a small hole near the bottom of the tank 1.5 m below the surface of water. Explain the principle used in deriving the velocity of water flowing from the hole.
