Water from a tap emerges vertically downwards with an initial speed of 1.0 m s–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 m s–2).
