showers in USA are regulated to have a maximum flowrate of 2.5 gpm (gallons/minute) at normal home water pressures, which are typicallyless than 80 psi. Water should be delivered at a velocity of at least 5 m/sto be effective for washing and rinsing purposes. If the tiny nozzles in ashowerhead each have a diameter of 0.75 mm, calculate the number ofnozzles needed to achieve an effective velocity
