Fluids are Moving and Grooving

C, E and F Blocks began a discussion on fluids in motion. We took time to contrast laminar and turbulent flow, described the ideal fluid model, discussed conservation of mass (as satisfied by the continuity equation) and dabbled in Bernoulli's Principle. Bernoulli's Principle explains a number of phenomena in real life that we outlined in class and a few more examples will be added tomorrow. Bernoulli also provides us with Bernoulli's equation, which will demonstrate how fluid systems satisfy the Law of Conservation of Energy.

B Block conducted a lab investigation on variations in fluid pressure with depth. The linear relationship derived from the experimental data nicely corroborated the basic pressure with depth formula: P = P_o + ρgh. We took time to examine the parts of that equation as demonstrated in the investigation and will take time tomorrow to see if you were able to successfully transfer that experience into problem-solving techniques for your homework problems. Then, it's onto fluids in motion!
