A plumbing system contains a junction with 4 pipes, as shown in the figure. Each pipe has a different mean velocit-
U1 = 55 cm/s
A1 = 10 cm²
%3D
U2 = 20 cm/s
A2 = 30 cm2
U3 = -10 cm/s
A3 = 40 cm2
U4 = ????
A4 = 5 cm2
Negative velocity indicates the fluid is moving out of the pipe.
Find the mean velocity in pipe 4 (the answer should be negative if the flow out of the pipe).
U, = 55 cm/s
A2 = 20 cm2
