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.

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 ?

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 flowing at high speed from a garden hose pipe tends to spread like a foundtion when held vertically up, but tends to narrow down when held vertically down. Statement-2 : In any steady flow of an incompressible fluid, the volume flow rate of the fluid remain constant.

During fall of water gently from a water-tap the stream gets thinner at the bottom. Why?

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 ?:
