Pumps in series and parallel pdf
Pumps can be arranged and connected in serial or parallel to provide additional head or flow rate capacity. Pumps in Serial – Head Added. When two (or more) pumps are arranged in serial their resulting pump performance curve is obtained by adding their heads at the same flow rate as indicated in the figure below.

A paper concerning isomorphism between the supervisor-supervisee relationship and the patient-therapist relationship.
In series arrangement, each pump handles same flow rate, but the total head produced by the combination of pumps will be additive. Since each pump generates a head H corresponding to a flow Q, when connected in series, the total head developed is Ht = H1 + H2, where H1, H2 are the heads developed by the pump in series at the common flow rate Q.
