Water stands at a depth of `15 m` behind a reservoir dam. A horizontal pipe `4 cm` in diameter passes through the dam `6 m` below the surface of water as shown. There is a plug which secures the pipe opening. Then find the friction between the plug and pipe wall.

The fresh water behind a reservoir dam is 15 m deep. A horizontal pipe 4.0 cm in diameter passes through the dam 6.0 m below the water surface as shown in the figure. A plug secures the pipe opening : (a) Find the friction force between the plug and the pipe wall. (b) The plug is removed. What volume of water flows out of the pipe in 3.0 hour ? Assume that reservoir is large. .

A fresh water on a reservoir is 10m deep. A horizontal pipe 4.0 cm in diameter passes through the reservoir 6.0 m below the water surface as shown in figure . A plug secures the pipe opening. . (a) Find the friction force between the plug and pipe wall. (b) The plug is removed. What volume of water flows out of the pipe in 1h ? Assume area of reservoir to be too large.

Water is flowing at a speed of 0.5 m/s through a horizontal pipe of internal diameter 3 cm. Determine the diameter of the nozzle if the water is to emerge at a speed of 3 m/s.

Doors of a dam are 20 m below the surface of water in the dam. If one door is opened, what will be the speed of the water that flows out of the door?( g=9.8m//s^2 )

Water is flowing through a horizontal pipe fixed at a height of 2 m above the ground as shown in Fig. 5.90. water strikes ground at a distance of 3m from the pipe. The speed of water as it leaves the pipe is:

An engine pumps water through a hose pipe water passes through the pipe and leaves it with velocity of 2 m/s. The mass per unit length of water in the pipe is 100 kg/m .What is the power of the engine ?
