Pressure at depth y using container of uniform cross section

Fluid Element from Hole at Depth y

Depth vs y Experiment

If we know the depth of water above an outflow hole and the rate at which the depth is changing, we can find the velocity of the water surface.

* Projectile analysis of stream, obtaining cross-sectional area from surface velocity

For an incompressible fluid in a region over which g does not vary greatly we can compare v, rho and P at two well-selected points to obtain information about the flow.

* Bernoulli's Equation:  Comparing two points, includes continuity equation

We can use a U tube connected to the gas inside a sealed bottle to observe pressure inside the bottle.

* U tube closed vs. open, squeezing bottle

* U tube analysis using Newton's Laws

* Analysis of depth vs y including energy and continuity equation

* Analysis of depth vs y for coke bottle (quiz form with solution)
