1. The problem statement, all variables and given/known data In a low-flow showerhead that contains 18 nozzle holes, the volume flow rate of the water is 4.00 L/min and the water maximum speed is 2.70 m/s. What is the diameter of each hole? Do not ignore viscosity of water. 2. Relevant equations Q=Av_max Q=((pi)r^2)v_max Q=(pi(r^4)/8nl)*(deltaP) v_max=2Q/(pi(r^2)) d=2r 3. The attempt at a solution Given: Q:4L/min = 6.6667E-5 m^3/s v_max=2.7 m/s v_average=v_max/2 v_average=1.35 m/s n(vescosity):8.90E-4 I am not quite sure where to start, I used the v_max equation, but I got the wrong answer. I know at some point I may need to divide by 18 for one nozzle.
