Water from a tap emerges vertically downwards with an initial speed of 1.0 msโ1 . The cross-sectional area of the tap is 10โ4 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 msโ2 )
(1) 5 ร 10โ4 m2
(2) 2 ร 10โ5 m2
(3) 5 ร 10โ5 m2
(4) 1 ร 10โ5 m2
