Paul E. TippensFluid MotionThe lower falls atYellowstoneNational Park: thewater at the top ofthe falls passesthrough a narrowslot, causing thevelocity to increaseat that point. In thischapter, we willstudy the physics offluids in motion.
Objectives: After completing thismodule, you should be able to:• Define the rate of flow for a fluid andsolve problems using velocity and cross-section.• Write and apply Bernoulli’s s equation forthe general case and apply for (a) a fluidat rest, (b) a fluid at constant pressure,and (c) flow through a horizontal pipe.
