Water is flowing at the rate of 15 km per hour through a pipe of diameter 14 cm into a rectangular tank which is 50 m long and 44 m wide. Find the time in which the level of water in the tanks will rise by 21 cm.

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