In chemistry and the principles of chemical engineering, regarding the suction height, what does absolute vacuum at the pump inlet mean? If a fluid flows stably in a circular pipe, what conditions must remain unchanged? ? Thank you
I’m not quite sure what you mean; please rephrase your question more specifically.
Most of them are centrifugal pumps; in the case of centrifugal pumps, the flow is stable and the data generally remains unchanged. . .
Absolute vacuum should be the inlet pressure of the pump, or in other words, the level of vacuum; it is a negative pressure condition. Only in this way can a pressure difference exist, allowing atmospheric pressure to force water into the pump. . . .
