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.. Centrifugal pumps in series are used to overcome larger system head loss than ...

Pumps are most often rated in terms of head and flow. In Figure 12, the discharge pipe end is raised to a height at which the flow stops, this is the head of the pump at zero flow. We measure this difference in height in feet (see Figure 13a). Head varies depending on flow rate, but in this case since there is no flow and hence no friction, the ...
The efficiency of a centrifugal pump can be defined as the ratio of the output power (water) to the input power (shaft). It can be demonstrated by using the following equation. Ef = PW / PS. Where, Ef is efficiency. Pw is the water power. Ps is the shaft power. In the U.S, the shaft power is the power given to the shaft of the pump in BHP ...

· The circuit diagram of the automatic plant watering system is shown in Fig. 2. The circuit comprises an Arduino UNO board, a soil moisture sensor, a servo motor, a 12V water pump and an L293D (IC1) motor driver IC to run the water pump. You can power the Arduino board using a 7V to 12V wall wart or plug-in adaptor or solar panel.
· Series and parallel circuits. 4. The components are connected end-to-end, one after the other. They make a simple loop for the current to flow round. If one bulb ''blows'' it breaks the whole circuit and all the bulbs go out. 5. The current has a choice of routes (paths). The components are connected side by side.

plotting the pump head in feet on the vertical scale and the distance from the pump on the horizontal scale. The horizontal scale on the pressure gradient diagram is used to separate the various pressure loss elements in the circuit. Figure 1 illustrates a pressure gradient diagram for a variable-primary-flow chilled water system.
