Problem 2 According to the EPA, the average shower in the United States lasts for about eight minutes and consumes roughly 60 liters of water. For the following questions, use the assumptions of ideal fluid flow (perfectly laminar flow, no losses due to viscosity, etc.). (a) Suppose that a shower head contains 48 pinholes, each with a diameter of 1.0 mm. What is the speed of the water stream as it exits from each pinhole? (Hint: 1.0 m =1,000 L.) (b) Suppose that the shower is being fed by standard inch copper pipe, which has an inner diameter of 13.8 mm. What is the speed of the water as it passes through this section of pipe? (c) What is the pressure in the section of pipe that is just behind the shower head, but at the same height as the shower head?
