Question

showers in USA are regulated to have a maximum flowrate of 2.5 gpm (gallons/minute) at normal home water pressures

, which are typically

less than 80 psi

. Water should be delivered at a velocity of at least 5 m/s

to be effective for washing and rinsing purposes. If the tiny nozzles in a

showerhead each have a diameter of 0.75 mm, calculate the number of

nozzles needed to achieve an effective velocity
