Oil at 20°C is flowing steadily through a 6-cmdiameter 33-m-long pipe. The pressures at the pipe inlet and outlet are measured to be 745 and 97.0 kPa, respectively, and the flow is expected to be laminar. Determine the flow rate of oil through the pipe, assuming fully developed flow and that the pipe is (a) horizontal, (b) inclined 15° upward, and (c) inclined 15° downward. Also, verify that the flow through the pipe is laminar.
