Seawater at 20◦C flows in a 6 m diameter inclined pipe, as illustrated in Figure EP 8.2. The pressure at point 1 is 5 × 105 N/m2 . The increase in elevation between points 1 and 2 is 0.088 m, the pipe length between points 1 and 2 is 16000 m, and the head loss due to pipe friction is 2 m. The Chezy coefficient, C for the pipe is 70 m1/2 s −1 . Assume turbulent flow. (a) Determine the friction slope at either points 1 or 2. (b) Determine the velocity and discharge in the pipe. (c) Confirm that the flow is turbulent. (d) 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.
