Question

I do not have the graph but can u give the best possible solution that applies to a typical graph.

Problem 2(35 A pump is placed in a pipe system in which the system curve is glven by the equation 1,-30 70 where H, is the head added by the pump in feet and Q is the flowrate through the sstem in cfs (ftis). The perfonnance curve of the pump is 11,-42-130 a. (1o pts) Determine the flowrate and head of the system h (15 pts.) The operator neods to increase the fow through the system and replaces the single pump with two pumps. The performance of the second pump is given on the graph below. How will operator comnect the pumps- in serles or in parallel? What are the nevw flowrate and head of the system? (10pts ) The operator also considers using a larger size impeller or opening up the discharge valve. Which of the two options (if any) would result in an increase of the head through the system? On a sqparate digram, sketch the new operating conditions and justify your answers c.
