In Conceptual Example 9.14, it was explained why a stream of water from a faucet necks down into a smaller cross-sectional area as it descends. Suppose at the top of the stream it has a cross-sectional area of 2.0 cm2, and a vertical distance 5.0 cm below the cross-sectional area of the stream is 0.80 cm2. What is
(a) The speed of the water and
(b) The flow rate?
