Question
Transcribed Image Text:A plumbing system contains a junction with 4 pipes, as shown in the figure. Each pipe has a different mean velocity
U1
55 cm/s
A1
10 cm?
U2 = 20 cm/s
A2 = 30 cm²
Uz = -10 cm/s
A3 = 40 cm?
U4 = ????
A4
: 5 cm?
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
%D
= 10 cm2
U, = 30 cm/
A4 = 5 cm2
U4 = ??
Az = 40 cm2
U3 = -10 cm/s
