Crude oil at 20◦C flows in a 6-m-diameter inclined asbestos cement pipe at a velocity of 2 m/sec, as illustrated in Figure EP 8.7. The pressure at point 1 is 5 × 105 N/m2 . The increase in elevation between points 1 and 2 is 0.04 m, and the pipe length between points 1 and 2 is 14,000 m. Assume the Hazen–Williams roughness coefficient is chosen to model the flow resistance. (a) Determine the major head loss due to the pipe friction (flow resistance) between points 1 and 2. (b) Determine the flow regime. (c) Determine the pressure drop between points 1 and 2 due to the increase in elevation and the pipe friction (flow resistance) between points 1 and 2.
