A sprinkler system pumps water through a large pipe inlet with a diameter (di). The pipe
then breaks into N narrow pipes (which have a diameter, o, and a length, L2), before the
water is released to the atmosphere, as shown in figure Q4. The entrance to the small
pipe from the large pipe has a loss coefficient of K. You may assume the flow is laminar
and fully developed everywhere in the system, and that any changes in height are
negligible.
The viscosity is not negligible.
a) Find an expression for the velocity of water leaving the sprinkler.
b) Find an expression for the gauge pressure at point A, a distance Lt upstream of the
narrow pipes. Express your answer in terms of the flowrate, Q.
