The friction pressure term used in the Bernoulli equation is a function of the friction head loss, the density of the fluid and the constant of gravity (g, 9.8 m.s-2). One can generally consider frictions negligible, if the surface to volume ratio and interactions within the system are limited, if the velocity of the fluid is low, or if the interactions between the fluid and the surface of the materials composing the pipes and other fluidics items are favourable, as in the case of water flowing in a hydrophobic channel. Assuming that the friction cannot be neglected, how would the friction pressure term change if, for a fixed pipe geometry, the velocity of the fluid was multiplied by 5?
