Practice Problem 13.9
Let's begin by looking at a flow problem in which the diameter of a pipe changes along the flow path. We will need to use both the continuity equation and Bernoulli's equation for this problem. Water enters a house through a pipe with an inside diameter of 2.0 cm at a gauge pressure of 4.0×105Pa (about 4 atm, or 60 lb/in.2). The cold-water pipe leading to the second-floor bathroom 5.0 m above is 1.0 cm in diameter (Figure 1) . Find the flow speed and gauge pressure in the bathroom when the flow speed at the inlet pipe is 2.0 m/s. How much time would be required to fill a 100 L bathtub with cold water?
Part A - Practice Problem:
Determine the gauge pressure for a 2-cm-diameter faucet located next to the washing machine in the basement, 2.0 m below where the pipe enters the house.
Express your answer to two significant figures and include the appropriate units.
