Water supplied to a house by a water main has a pressure of 3.00105 N/m2 early on a summer day when neighborhood use is low. This pressure produces a flow of 20.0 L/min through a garden hose. Later in the day, pressure at the exit of the water main and entrance to the house drops, and a flow of only 8.00 L/min is obtained through the same hose. (a) What pressure is now being supplied to the house, assuming resistance is constant? (b) By what factor did the flow rate in the water main increase in order to cause this decrease in delivered pressure? The pressure at the entrance of the water main is 5.00105 N/m2, and the original flow rate was 200 L/min. (c) How many more users are there, assuming each would consume 20.0 L/min in the morning?

In one form of plethysmograph (a device for measuringvolume), a rubber capillary tube with an inside diameter of1.00 mm is filled with mercury at 20°C. The resistance of themercury is measured with the aid of electrodes sealed into theends of the tube. If 100.00 cm of the tube is wound in a spiralaround a patient’s upper arm, the blood flow during a heartbeatcauses the arm to expand, stretching the tube to a lengthof 100.04 cm. From this observation, and assuming cylindricalsymmetry, you can find the change in volume of the arm,which gives an indication of blood flow. (a) Calculate the resistanceof the mercury. (b) Calculate the fractional change inresistance during the heartbeat. Take ρHg = 9.4 x 10-7 Ω ⋅ m.Hint : Because the cylindrical volume is constant, V = Ai Li = AfLfand Af = Ai(Li /Lf ).
