virtaustilakäyrin
A virtaustilakäyrin, often translated as flow state curve or characteristic curve, is a graphical representation used in fluid dynamics and engineering to describe the performance of a centrifugal pump or fan. It illustrates the relationship between the flow rate (virtaama) and the total head (nostokorkeus) or pressure developed by the machine at a constant speed.
The curve typically starts at zero flow rate, where the pump or fan produces its maximum head,
The shape of the virtaustilakäyrin is crucial for selecting the appropriate pump or fan for a specific
The virtaustilakäyrin can also illustrate efficiency, power consumption, and cavitation characteristics at different flow rates. These
