If you turn on a water faucet so that the water flows smoothly, you should observe that the cross-sectional area of the water stream decreases as the stream drops. At a particular point, the flow speed is 40.0 cm/s and the stream has a cross-sectional area of 2.00 cm2. Use g = 9.80 m/s2. At a point 7.00 cm below the first point, determine the following. (a) the flow speed cm/s (b) the cross-sectional area of the stream cm2

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
