Document Summary
Fluid low can be either: in streamlines (only deal with this type, in turbulent low (requires navies stobes and large computer. Equaion of coninuity: rate of mass inlux. M1/ t: equated to rate of mass elux. M2/ t p1a1v1= p2a2v2: for an incompressible luid p1=p2. When there is a height diference or when there is a pressure diference or when there is a velocity diference, we use bernoulli"s equaions: b. eqn derived from. W = ke + pe: you get: N. b. for incompressible (densiiy = p = constant) luids. If any of those variables are constant from before and ater, you can cancel them!! 2 + pgy2: if no diference in height ie. y1=y2. Rearranged v2 = v1(a1/a2) so put those two together: and get: p 2. = a 2: no diference in velocity. 2 + pgy1 = p2 + pv2. So you get this in brackets is same as the height, h.
