A water tank is constructed on the top of a building. With what speed will the water come out of a tap 6.0 m below the water level in the tank? Assume steady flow and that the pressure above the water level is equal to the atmospheric pressure

Text Solution

Verified by Experts

The velocity is given by Torricelli's theorem
`v=sqrt(2gh)`
`=sqrt(2xx(9.8ms^-2)xx(6.0m))~~11ms^-1`

Water leaks out from an open tank through a hole of area 2mm^2 in the bottom. Suppose water is filled up to a height of 80 cm and the area of cross section of the tankis 0.4 m^2 . The pressure at the open surface and the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank. a. Find the initial speed of water coming out of the hole. b. Findteh speed of water coming out when half of water has leaked out. c. Find the volume of water leaked out during a time interval dt after the height remained is h. Thus find the decrease in height dh in term of h and dt. d. From the result of part c. find the time required for half of the water to leak out.

Water is filled in a rectangular tank of size 3mxx2mxx1m . a) Find the total force exerted by the water on the bottom surface of the tank. b) Consider a vertical side of area 2mxx1m .
