Pump characteristic curve and device characteristic curve
Thread Content
Pump head = difference in static pressure energy + difference in potential energy + difference in kinetic energy; system head = difference in static pressure energy + difference in potential energy + head loss due to piping. My understanding: the difference in kinetic energy is the velocity head, given by the formula V²/2g. Does pipeline loss refer to the loss of pressure energy as it is converted into kinetic energy? Who can explain the pump characteristics and device properties in simple terms? I find it difficult to understand the information available; I would be extremely grateful! :)
Simply put, the static pressure difference refers to the static pressure measured at the two points using pressure instruments. The kinetic energy difference is caused by variations in flow velocity when the pipe diameters at those two points are different. As for the potential energy difference, it’s simply due to the difference in elevation between the two points
I think your own understanding is quite accurate
