Suppose water is leaking from a tank through a circular hole of area Ah at its bottom. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cAh 2gh , where c (0 < c < 1) is an empirical constant. A tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its...

A closed and elevated vertical cylindrical tank with diameter 80 cm contains water to a depth of 0.900 m . A worker opens a circular hole with diameter 12 cm in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains a gauge pressure of 5.00×103Pa at the surface of the water. Ignore any effects of viscosity ( ½w = 1000 kg=m3 ). a) (12 points) Just after the...

A tank holds 100 gallons of water, which drains from a leak at the bottom, causing the tank to empty in 40 minutes. According to Toricelli's Law, the volume V of water remaining in the tank after t min is given by the function V = f(t) = 100 1 − t 40 2 . (a) Find f −1. f −1(V) = $$ Correct: Your answer is correct. What does f −1 represent? f −1 represents the rate at which...
