Unformatted text preview: Comment: Assume the submarine is running in deep water, i.e. it is deep enough not to cause any surface waves, etc. In other words, treat it as flow around a completely submerged object. Problem 7. Work Problem 7.47. Comment: A good example of the power of dimensional analysis and modeling to get information on a very complicated problem. Problem 8. Work Problem 7.63 . Note: This is another dagger problem. In working it, make some order of magnitude estimates of the size of an oil tanker and the wind velocities and wave heights on Goleta Beach. Assume that your fluids professor has thrown his weight around and obtained permission to use of the floor space in one of the labs in Engineering II. Youll need fans to model the wind and a water tank with a sloping beach to model the ocean flow. There will be Reynolds and Froude numbers galore! Examine the ability to model this situation by making quantitative estimates: in other words, put some numbers to it....
