Referring to Example 5. 11 , plot the system head curve with a spreadsheet program. On the same graph, plot the pump characteristic curve for pump III at a speed of 3,850 rpm. Now answer the following questions.
(a) What is the shape of the system curve? Why does it take this shape?
(b) What is the shape of the characteristic curve? Why does it take this shape?
(c) What flow rate produces the highest total head on the pump characteristic curve? What physical meaning does this have?
(d) What is the intersection point of the two curves? Does it meet the design conditions?
