Rate of Flow
Bernoulli's Principle
(a) fluid at rest
(b) a fluid at constant pressure
Lockstep
Particles never jostle or roll against each other
Turbulence flow
Crazy differential equations
The fluid are incompressible
No internal friction
what is flow
rate R
volume V
cross section A
per unit of time T
V=Avt
Define volume by locking in two parallel surfaces
Velocity times area
--------------------------------------------------------------------------------------------------------------------------------------------------
Incompressible
Smaller: Speeds up
Larger: Slows down
R=v1A1=v2A2 -----> v1d1^2 = v2d2^2
Manifests the same as amps/volts
Pa-Pb = pgb
Venturi Meter
Force of Suction
Volume flow rate has to increase, and then increase in velocity
Greater internal
Net Work= P1V-P2V = (P1-P2) V
Net Work deltK+deltU also (P1-P2)V
(.5mv2^2-.5mv1^2)
p = m/V then simplify
v= sqrt 2gh
