Task 16 On a permanent pipeline

Task 16 Oil with a density of p = 860 kg/m3 is pumped through a pipeline of constant diameter and length L = 56.4 km . The starting point is 120 m higher than the end point. Determine the hydraulic slope if it is known that the pressure at the starting point p1 = 3.0 × 106 Pa, and at the end point p2 = pa.
