An outlet pipe in the roof with length 13m and breadth 11m was closed at the time of rain fall. After rain fall, it was seen that water habing logged in the roof with 7cm depth. The length of diameter of outlet pipt is 7cm and water comes our cylindrically with 200m length/min. Calculate the time required is drainout whole amount of water after opening the pipe.

A hot water system (Geyser) consists of a cylindrical pipe of length 14 m and diameter 5 cm. Find the total radiating surface of hot water system.

A right circular cylindrical tank of 9 metre height is filled with water. Water comes out from there though a pipe having length of 6 cm diameter with a speed of 225 metre per minute and the tank becomes empty after 2 hrs. 24 minutes. Calculate the length of diameter.

There are some water in a long gas jar of 7 cm diameter. If a solid right circular cylindrical pipe of iron having 5 cm length and 5*6 cm diameter be immersed completely in that water, calculate how much the level of water will rise.

The depth of a cuboid pond with length of 20 m and breadth of 18.5 m is 3.2 m, determine the time required to irrigate whole water of the pond with a pump having the capacity to irriagate 160 kilolitres water per hour. If that quantity of water is poured on a paddy field with a ridge having the length of 59.2 m and breath of 40 m, then what is the depht of water in that land ? [Let 1 cubic metre=1 kilolitre]

A right circular cylindrical tank of 9 metres height is filled with water. Water comes out from there through a pipe having length of 6 cm diameter with a speed of 225 metre per minute and the tank becomes empty after 2 hours 24 minutes. Calculate the length of radius of the tank.

A steel wire of length 2 m and of diameter 0.8 mm is rigidly fixed at two ends horizontally ,when a load is suspended from the mid-point of the wire, a depression of 1 cm is produced. Calculate the amount of load attached, if Young's modulus for steel is 20 times 10^11 dyn .cm^-2 .

A body of mass 2kg and density 2.7 g. cm^-3 is suspended by a steel wire of length 1 m and radius 1 mm. IF the body is completely immersed In water, what will be the change in length of the wire? Y of steel =2 times 10^2 dyn.cm^-2 and g=980 cm.s^-2

Water flows at a speed of 10 m per minute through a right circular pipe of diameter 5 mm . In how much time a tank of conical shape having diameter 40 cm and depth 24 cm will be fulfilled completely by this pipe ?

A vibrating tuning fork of frequency 340 Hz is held over a cylindrical pipe. The length of the pipe is 120 cm . Now water is slowly poured into it. What should be the water level at which resonance will occur ? Velociy of sound in air = 340 m*s^(-1) .
