$(1)$ Water flows viscously into a chamber with a

pressure $P_1=100$kPa, velocity $V_1=15\frac{m}{s},$ and

inlet diameter $d_1=2cm.$ The flow exits through two

outlets of identical diameters $d_2=d_3=2cm.$ If the

flow is steady, calculate the exit velocities at the two

outlets if they can be assumed to be the same.

What are the exit pressures?
