Water flows through a pipe bent at an angle `alpha` to the horizontal with velocity v . Calculate the force exerted by the water on the bend of the pipe of area of cross - section S .

Water flowing through a horizontal pipe line having a constriction. Then,

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 flows through a tube assembly as shown in the fig. Speed of flow (marked as V and 2V ), cross sectional area (A, A/2 and A/4) and the angles between segments has been shown in fig. Calculate the force applied by the water flow on the tube. Take density of water to be rho .

Water flows through a horizontal pipe of varying area of cross-section at the rate 5 cubic metre per minute. What is the velocity of water at a point where pipe radius is 10 cm?

Lasya is watering the plants in her graden with a pipe of area of cross- section 'A' and observed that the force of water from the pipe is 'F' .Find the change in area of caross section of the pipe to attain a pressure difference which is 1.5 times that of the intial.

Water is flowing through a pipe of constant cross-section. At some point the pipe becomes narrow and the cross-section is halved. The speed of water is
