Answer the marked (*) questions using complete solutions. 15. Water enters a house through a pipe with diameter of 2.0 cm at an absolute pressure of 4.0 × 105 Pa. A 1.0 cm-diameter pipe leads to the second floor bathroom 5.0 m above. When the flow speed at the inlet pipe is 1.5 m/s, what is the flow speed in the bathroom? Solution: Recall the continuity equation A¡º1 the bathroom pipe. We have Azv2, where point 1 is the inlet pipe and point 2 is A1 A2 Plugging in the values, we get vz = 6.0 m/s. The volume flow rate is A2v2 = 4.7 × 10–4m³ /s. Question: 16.* (Continuation) What is the pressure in the bathroom pipe?
