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 steady. The cross-sectional area of the stream 0.15 m below the tap is (take g = 10 ms–2)
- 5.0 × 10–4 m2
- 1.0 × 10–5 m2
- 5.0 × 10–5 m2
- 2.0 × 10–5 m2
Answer
(C) 5.0 × 10 –5 m 2
