A drum of 30 cm radius has a capacity of 220 `dm^(3)` of water. It contains 198`dm^3` of water and is placed on a solid block of exactly the same size as of drum .If a small hole is made at lower end of drum perpendicular to its length, find the horizontal range of water on the ground in the beginning. Given g = 980 cm `s^(2)`.

A drum of 40 cm radius has a capacity of 440 dm^(3) of water. It contains 396 dm^(3) of water and is palece on a solid block of exactly the same size as of drum. If a small hole is made at lower end of the durm perpenduclar to its length , find the horizontal range of water on the ground in the beginning. given g=10 m//s^(2) .

A hollow sphere which has a small hole in its bottom in water to a depth of 30 cm before any water enters in it. If the surface tension of water is 75 dynes/cm then find the radius of the hole in metres (taking g=10m//s^(2))

The level of water in a tank is 5 m high. A hole of area of cross section 1 cm^(2) is made at the bottom of the tank. The rate of leakage of water for the hole in m^(3)s^(-1) is (g=10ms^(-2))

A solid is in the form of a right circular cone mounted on a hemisphere. The radius of the hemisphere is 3.5cm and the height of the cone is 4cm. The solid is placed in a cylindrical tub, full of water, in such a way that the whole solid is submerged in water. If the radius of the cylinder is 5cm and its height is 10.5cm, find the volume of water left in the cylindrical tub. (U s epi=(22)/7)

A vessel has a small hole at its bottom. If water can be poured into it upto a height of 7 cm without leakage (g=10ms^(-2) ) the radius of the hole is (surface tension of water is 0.7Nm^(-1) )

A garden pipe has an internal diameter of 4 cm. It is connected to a lawn sprinkler that consists of 24 holes at the other end. Each hole is of radius 0.06 cm. If the water in the pipe has a speed of 80 cm s^(-1) , find its speed through sprinkler holes.

A 16cm^(3) of water flows per second through a capillary tube of radius r cm and of length 1 cm, when connected to a pressure head of h cm of water. If a tube of the same length and radius r//2 is connected to the same pressure head, find the mass of watear flowing per minute through the tube.
