Question

I need help finding the mean velocity in pipe 4 

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 A, = 10 cm? U2 = 20 cm/s %3D %3| A, = 30 cm? U3 = -10 cm/s Az = 40 cm? U = ???? 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 A, = 10 cm2 U2 = 30 cm/ A4 = 5 cm2 U4 = ?? %3D Az = 40 cm2 %3D Uz = -10 cm/s O a. -310 cm/s оь. -230 ст/s O . 230 cm/s O d. -150 cm/s O e. 150 cm/s O f. 0 g. 310 cm/s
