solve for part E

Consider the following system, a pipeline with three equal bends and a butterfly valve attached to a very larger reservoir of fluid. H=20m h = 3.8m a=0.5m dA -0.13m L1 - 2m, L: -1.5m, L-2.8m, L - 2.5 m do... dj-0.15 m f=0.03 KA -0.6, Ke -0.25, Ku - 0.15 Ko =0.08 (fully opened) p-1000 kg/m'; P. - 1 bar A. For frictionless flow, find the velocity at points A through J. B. For frictionless flow, find the pressure at point A. C. For real flow, find the velocity at points A through J. Assume the butterfly valve is fully open. D. For real flow, find the volumetric flow rate in the pipeline for different values of the angle of the butterfly valve (use attached Table of friction factors). Divide these values by the value for the fully opened valve. Plot this ratio versus the angle. E. Assume that a pump is inserted into the piping system at point C. The pump specific shaft work is 3 mls? (n=0.8). Find the velocity at points A through J assuming a fully open butterfly valve.
