Water is being pumped (at Q) from a reservoir to a nearby storage facility for a local farm. Thewater level in the reservoir varies throughout the year. When it is considered “full” the change inelevation from the top of the water line to the centerline of the pipe at (2) is h. The pipe is madeof welded steel. Assuming there are both major and minor losses, determine the pressure in thepipe at (2).Clearly state the source(s) of minor losses.Use the Haaland and Darcy-Weisbach equations.Flowrate (Q), elevation difference (h), head from pump (hp), pipe length (L), and diameter (D)are given below. State all assumptions. Q =0.54 m^3/s, h =3.5 m, h_p=47.5 m, L = 23.33 m, D = 0.467m
