When a smooth-flowing stream of water comes out of a faucet, it narrows as it falls. Explain.

Solution 29DQ Introduction We have to discuss why the cross section decreases as the water flows down from the faucet in steady state flow. Step 1 From the continuity equation we can write that A1 1= A 2 2 Av = constant 1 A v That is for steady streamline flow the cross sectional area is inversely proportional to speed of the fluid....
