A water jet, 0.002

in cross section, issues with a velocity of 4 m/s, and is directed to an open tarik, as shown in Figure P5.13. The water is extracted from

the rank at a constant rare of 0.01 m3 /s. What time is needed co evacuate the rank if it contains 200 m3 of water?

A112:

A cylindrical water rank with a diameter of2.5 fr has a side hole of 4-in diameter and a bottom hole 6 inches in diameter. The water enters from the side hole and leaves from the bottom hole, as shown in Figure P5.14. The velocity of water at the outlet is V = (2gh)°-5, where h is the height of the water surface above the outlet. At a certain rime, where h = 1.25 fr, the water level was rising at a rate of 0 .5 in/s. Assuming that the fluid is incompressible, determine the water velocity through the inlet.
