Document Summary

Assume friction = 0, and fluid is newtonian for a tube, P1 + density*g*h1 + density*v1 h is defined as the height of the fluid in relevance to gravity, irrelevant of walls. Meanwhile, the kinetic energy of a mass at a velocity = mv*v*, thus. Principle for a static fluid = density*g(h2 - h1) = p1 - p2 = - p. In a perfect horizontal cylinder-shaped tube, bernoulli"s is. Density*v1 v1 thus if p = 0 ; v = 0, meaning if there is no change in pressure at ends of tube, there will be no flow. Torricelli saw a fluid rushing out of an open-topped tank and wondered about the velocity as the height of the fluid changed, and found this principle: P1 + density*g*h1 + density*v1 v1 is the speed at which the fluid is going down at the top of the bucket while v2 is how fast its rushing out in a stream assume h1=h and h2=0.
