Also, indicate the direction of the velocities through these surfaces. Indicate the open control surfaces, and show the positive direction of their areas. Outline the control volume that contains the water in the pipe system. Water flows steadily through the pipes with the average velocities shown. However, the water flows in and out of the control volume through the open (inlet and outlet) control surfaces. SOLUTION Since the flow is steady, no local change occurs.
