Document Summary
Exam #3: write all equations in their most general form and then begin simplifying. State/list all your assumptions when you are simplifying the equations: check your units, box your answers and provide units. Gravitational constant: g = 9. 81 m/sec2 = 32. 2 ft/sec2 lbf = mass (slugs) x g (ft/sec2) Short answer (3 points each: a reynolds number can be interpreted as the ratio of what two types of forces, the flow in a 1 meter diameter pipe is fully laminar (i. e. , the re is < 2000). A model pipe is built that is 1/10 the size of the prototype. If the wave period in the model is 2 seconds, what is the wave period in the prototype? tp = 10 sec (16 points) two horizontal parallel plates are spaced 0. 01 ft apart. The pressure decreases at a rate of 10 psf/ft in the horizontal x direction in the fluid between the plates.
