A liquid flowing out of a very small opening of a tube of a tab comes out in the form of fine drops and not as a continuous stream.Why?

In guttation water comes out in the form of a liquid from the plant .

The liquid coming out of hydathode of grasses is:

A fluid flowing out of a small hole in a vessel results in a backward thurst on the vessel.

Why does the roots of Rhizophora come out of the ground ?

Water is slowly coming out from a vertical pipe. As the water descends after coming out its area of cross section reduces. Explain this on the basis of the equation of continuity.

Figure shows a liquid being pushed out of a tube by pressing a piston. The area of cross section of the piston is 1.0 cm^2 and that of the tube at the outlet is 20 mm^2 . If the piston is pushed at a speed of 2cms^-1 . What is the speed of the outgoing liquid?

X- rays coming out of an X -ray tube ______ .

A stopper is inserted in a small hole of the glass tube of the mercury barometer below the top level of the mercury in it. What happens when you pull out the stopper from the glass tube?

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 drop of oil placed on the surface of water spreads out. But a drop of water place on oil contracts to a spherical shape. Why ?
