There is a hole at the bottom of a large open vessel. If water is filled upto a height h, it flows out in time t. if water is filled to a height 4h, it will flow out in time

A hole is made at the bottom of a large vessel open at the top. If water is filled to a height h it drain out completely in time t. The time taken by the water column of height 4h to drain completely is (a). sqrt(2t) (b). 2t (c). 2sqrt(2t) (d). 4t

A hole is made at the bottom of a large vessel open at the top. If water is filled to a height h it drain out completely in time t. The time taken by the water column of height 2h to drain completely is (a). sqrt(2t) (b). 2t (c). 2sqrt(2t) (d). 4t

There is a hole of area (1)/(25)cm^(2) in the bottom of a cylindrical vessel containing fluid up to height h . The liquid flows out in time t . If the liquid were filled in the vessel up to height 4h , then it would flow out in time

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

consider a cylinder of radius R. At its bottom, there is a hole of radius r. the cylinder is filled upto the height h and the hole is opened. If t is the time in which the cylinder is emptied, then find the relation between t and h.
