Problem
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 steady. The cross-sectional area of the stream 0.15 m below the tap is
(1) 5.0×10−4 m2
(2) 1.0×10−5 m2
(3) 5.0×10−5 m2
(4) 2.0×10−5 m2
