Webb17 juli 2024 · The difference in height the liquid can overcome depends on the power of the pump, the density of the fluid to be pumped and the volume flow rate. To show this, we consider a vertical pipeline. Through this pipe, a fluid of density ϱ is pumped up from a tank. The water is discharged at the open end of the pipe.

"WebbBernoulli’s Theorem (Daniel Bernoulli 1700 - 1782) is discussed in Block 4 - Flowmetering. D’Arcy (D’Arcy Thompson 1860 - 1948) added that for fluid flow to occur, there must be more energy at Point 1 than Point 2 (see Figure 10.2.3). The difference in energy is used to overcome frictional resistance between the pipe and the flowing fluid. " - Pipe flow comparison
