The mathematical form of Bernoulli's equation is given as: Where, p= pressure inside the pipe ρ =density of the fluid g =gravitational constant v = velocity z=elevation or headwater in Syringe A and the tube that follows it. As water is virtually incompressible, the pressure spreads through the water into Syringe B. The water pushes against the plunger in Syringe B with equal pressure, exerting a “load force” on it. However, Syringe B has a plunger with a bigger cross-sectional area than Syringe A. Bernoulli's principle states the pressure would reduce as velocity of the fluid increases, but to me it seems intuitive that the pressure would increase because the air is being forced into the tube (with resistance). 0 comments. 100% Upvoted.

The mathematical form of Bernoulli's equation is given as: Where, p= pressure inside the pipe ρ =density of the fluid g =gravitational constant v = velocity z=elevation or headwater in Syringe A and the tube that follows it. As water is virtually incompressible, the pressure spreads through the water into Syringe B. The water pushes against the plunger in Syringe B with equal pressure, exerting a “load force” on it. However, Syringe B has a plunger with a bigger cross-sectional area than Syringe A. Bernoulli's principle states the pressure would reduce as velocity of the fluid increases, but to me it seems intuitive that the pressure would increase because the air is being forced into the tube (with resistance). 0 comments. 100% Upvoted.
