Water from a tap emerges vertically downwards with an initial speed of 1.0 ms^–1
. The cross-sectional area of
the tap is 10^–4 m². Assume that the pressure is constant throughout the stream of water and that the flow is streamlined. The cross-sectional area of the stream, 0.15 m below the tap would be : (Take g = 10 ms^–2)
