Assignment:
Question. A dam to create a large fresh water lake is constructed. It will be approximately 14 meters deep. A horizontal pipe 1.2 meters long and 4 cm in diameter will pass through the dam at a depth of 7 meters to allow for release of the water in emergencies and for sampling. In normal situations, a plug will secure the pipe opening.
Explain the calculations in detail.
(a) What will be the total force on the left side of the plug?
F(left) = ____________________ N
(b) What is the total force on the right side of the plug?
F(right) = ____________________ N
(c) What is the gauge pressure on the plug?
Pgauge = ____________________ Pa
(d) If the plug were to be removed, how much water would flow out in 3 hours?
¦¤VOL = ____________________ m3
