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
