All the relevant characteristic details of the other pipes and the single pump details as well are given below. Note that, Ek values are the total minor loss coefficients along each of these pipes. a) Determine the proper pumping system along pipe 3, (15 p) b) The flow amounts and directions along pipes 1, 2, and 4, (15 p) c) Based on your calculations, suggest a possible hydraulic appurtenance (a pump or a valve) for the point E (?) and find its value that satisfies you calculations.
