Task 21 On a pipeline of constant cross-section

Task 21 Oil with a density of p = 890 kg/m3 is pumped through a pipeline of constant cross-section with a length of L = 5800 m. The starting point of the pipeline is below the end point by 42 m. The hydraulic slope is equal to i = 0.006. Determine the necessary pressure P1 at the starting point of the pipeline to obtain excess pressure at the end point P2 = 2 at
