1. Water flows in a constant-diameter pipe with the following conditions measured: At section (a) pa = 32.4 psi and za = 56.8 ft; at section (b) pb = 29.7 psi and zb = 68.2 ft. Is the flow from (a) to (b) or from (b) to (a)? Explain.
2. For laminar flow in a round pipe of diameter D, at what distance from the centerline is the actual velocity equal to the average velocity?
