Lab 3-pumps In Series And Parallel

HM Base module for experiments in fluid mechanics. In complex systems, pumps can be connected in series or in parallel. In series operation the heads are added together and in parallel operation, the flow rates of the pumps are added. Series and parallel configuration of pumps behave similar to series and parallel configuration of electric resistances in electric circuits. The pump correlates with the electric resistance, the flow correlates with the electric current and the head with the voltage.

Sometimes the required operating conditions for a system are beyond the reach of a single, standard pump. Rather than purchasing a heavy duty pump that may be far more than you need, consider taking advantage of system design strategies to combine simple pump performances that add up to the necessary requirements. The following post walks you through pumps in series and in parallel so that you can get your ducks… I mean pumps… in a row — or side by side, depending on the application. Putting your centrifugal pumps in series, or connected along a single line, will let you add the head from each together and meet your high head, low flow system requirements. This is because the fluid pressure increases as the continuous flow passes through each pump, much like how a multi-stage pump works. For example, if two of the same pumps are in series, the combined performance curve will have double the head of a single pump for a given flow rate. For two different pumps, the head will still be added together on the combined pump curve, but the curve will most likely have a piecewise discontinuity meaning to curve with protusions as pictured in in the 2nd pump curve below.

In order to illustrate the concept of parallel pumping, we'll use two pumps, each sized for one-half of full system flow. Note that for two identical pumps in parallel,​.

A self contained floor standing mobile unit consisting of a water reservoir, two pumps and motors and a Venturi meter for a comprehensive range of investigations into the performance and characteristics of two centrifugal pumps in both series and parallel. A compact, mobile and fully self-contained centrifugal pump test set, that allows students to find the characteristics of centrifugal pumps working alone or in series or parallel. It also allows students to see and hear cavitation and understand the use of a Venturi meter and differential pressure measurement to find flow rate. Two bearing-mounted motors drive each pump independently.

Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone. for two identical pumps in series the head will be.
