say 1 and 2, depends on the shape of the system curve (see next Figure). The points that lie on system curve A will all be approximately at the same efficiency. Whereas the points that lie on
The System Curve A fluid flow system is characterized with theSystem Curve- a graphical presentation of theEnergy Equation. The system head visualized in the System Curve above is a function of elevation - or the static head and themajor and minor lossesin the system and can be expressed as:...
The interaction of the systems curve and the combined pump curve are at point [1]. This describes the total flow in the system, comprised of flow [3] plus flow [2] If only pump A operates, and then the system flow is point [5]. If only pump B operates, then the flow is point ...

One of the key aspects of a hydronic mechanical system is the pump. If the pump isn't designed or selected correctly, the entire system will not function. Using general principles and rules of thumb to design a pump may work earlier on in design. However, thoroughly understanding how a pum...
Hopefully with sufficient test data I should be able to tell how the pump behaves at low flow rates and thus get a better idea of the curves to be used in general using free curve fitting software or a program such as MATLAB or Excel. I will also keep in mind the realities of the ...

For traditional use, it is common to use the general pump model or polynomial curves to fit the system characteristics (Wu et al., 2015; Lai et al., 2020; Shankar et al., 2017; Carravetta et al., 2017). Such models have simple structures and do not require high-quality initial data...
Every fire pump system produced goes through quality and testing process to ensure it meets the required level of compliance standard. Performance Test Each pump produced, undergoes performance tests as follows, Operation Test Performance curves are plotted showing the Efficiency, Brake Horsepower (kW)...
A system for pumping of liquid under pressure, in which a pressure switch is adapted to control the starting and stopping of the pump within a safe pressure range, and in the event of malfunction of the pressure switch, the service line and associated plumbing is isolated from the pump to ...
