Figure shows how the stream of water emerging from a faucet necks donw as it falls. The area changes from `A_(0)` to A through a fall of h. At what rate does the water flow from the tap ?

Why does a stream of water from a faucet become narrow as it falls?

Fig shows how the stream of water emerging from a faucet "necks down" as it falls . This change in the horizontal cross- sectional area is characteristic of any laminar (nonturbulant) falling stream because the gravitational force increases the speed of the stream . Here the indicated cross-sectional areas are A_(0) = 1.2 cm^(2) and A = 0.35 cm^(2) . The two levels are separated by a vertical distance h = 45 mm . What is the volume flow rate from the tap ?

Statement-1: The stream of water emerging from a wate tap "necks down" as it falls. Statement-2: The volume flow rate at different levels is same.

When a bucket full of water is rotated,water does not fall from it.Why?

Water falls from a top down the streamline,

Water is falling from the top of a high water fall. On falling :

Take a plastic bottle . Pierce it with a thick needle at the points 1,2,3 as shown in thefigure . Fill water in the bottle upto full height . As shown in the figure , water jets will be seen emerging and projecting out . The water jet emerging from the hole at the top will fall closest to the bottle . the jet from the lowest hole falls farthest from the bottle . also , jets coming out from the two holes at the same level fall atthe same distance from the bottle . what is understood from this ?:

What is the change in temperature of water when it falls from the top to the bottom in a waterfall?
