(a) Water flows out of a shower in a typical house at a rate of 20 liters/min. If this shower is fed through a pipe that is 2.2 cm in diameter and 19 m from the high-pressure water tank, what is the difference between the pressure in the tank and atmospheric pressure? Assume the tank is at the same height as the shower and assume an ideal fluid.
Pa
(b) What pressure difference is needed for an energy-efficient shower head, which limits the flow rate to 4.0 liters/min?
