A water fountain on the ground sprinkles water all around it. If the speed of water coming out of the fountains is v, the total area around the fountain that gets wet is:

The water that comes out during guttation is

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.

A tank of height H and base area A is half filled with water and there is a small orifice at the bottom and there is a heavy solid cylinder having base area (A)/(3) and height of the cylinder is same as that of the tak. The water is flowing out of the orifice. Here cylinder is put into the tank to increase the speed of water flowing out. The speed of water flowing out of the orifice after the cylinder is kept inside it is

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 steadyy flow and that the pressure above the water level is equal to the atmospheric pressure

The water held tightly by the soil particles around them is known as :

Shows a large closed cylindrical tank containing water, Initially the air trapped above the water surface has a height h_(0) and pressure 2p_(0) where p_(0_ is the atmospheric pressure. There is a hole in the wall of tank at a depth h_(1) below the top from which water comes out. A long vertical tube is connected as shown. (a) Find the height h_(2) of the water in the long tube above the top initially. (b) Find the speed with which water comes out of hole.(c)Find the height of the water in the long tube above the top when the water stops coming out of the hole.
