If the performance curve of a certain pump model is given by

hp = 30 − 0.05Q 2

where hp is the head added in m and Q is the flow rate in L/s, what is the performance curve of a pump system containing n of these pumps in series? What is the performance curve of a pump system containing n of these pumps in parallel?
