$4\mathrm{.}10$

Find $V$ for this mushroom cap on a pipeline.

$4\mathrm{.}15$ Water flows through a tee in a horizontal pipe system as shown in the figure. The incoming

velocity is $15f\frac{t}{s},$ the pressure is $20$ psi $,$ and the pipe diameter is $12$ in $.$ Each branch of the tee is $6$ in$.$ in

diameter and the velocities in the branches are the same. Determine the magnitude and direction of the

force of the water on the tee.
