Water is flowing through a horizontal pipe at the rate of 1/3 litre per second. Calculate the velocity of flow at a point where diameter is 3 cm.

Water is dripping out from a conical funnel at a uniform rate of 4cm^(3)/cm through a tiny hole at the vertex in the bottom.When the slant height of the water is 3cm ,find the rate of decrease of the slant height of the water- cone.Given that the vertical angle of the funnel is 120^(@).

The rate of flowing of water from the orifice in a wall of a tank will be more if the orifice is

Water is dripping out from a conical funnel of semi-vertical angle (pi)/(4) at the uniform rate of 2cm^(2)/sec in its surface area through a tiny hole at the vertex in the bottom.When the slant height of the water is 4cm ,find the rate of decrease of the slant height of the water.

Water is flowing at the rate of 5 km per hour through a pipe of diameter 14 cm into a rectangular tank which is 25 m long and 22 m wide. Determine the time in which the level of water in the tank will rise by 21 cm. (take pi = 22/7)

Water is flowing at the rate of 5 km/hour through a pipe of diameter 14 cm into a tank with rectangular base which is 50 m long and 44 m wide. Find the time in which the level of water tank rises by 7 cm. (Use pi = 22/7 )
