Water at 20^{\circ} C flows in a 3.5-m-diameter inclined straight pipe section at a flowrate of 2.6 m^{3} /sec, as illustrated in Figure EP 5.1. The pipe length between points 1 and 2 is 900 m, and the Chezy coefficient, C for the pipe is 60 m^{1/2} /s^{−1} . The elevations of points 1 and 2 are 1.3 m and 1.8 m, respectively, and the pressure at point 1 is 3 × 10^{4} N/m^{2} . (a) Determine the friction slope at any point in the straight pipe section. (b) Determine the head loss due to pipe friction between points 1 and 2. (c) Determine the pressure drop at point 2 due to the pipe friction.
