Unformatted text preview: Name: ___________________________ Page 1 ME 3720B Intro Fluid Thermo Eng – Spring 2008 SAMPLE Test #3 (50 minutes, open textbook only) You do not need to follow any specific procedure. Use a hand-held calculator. Problem 1. (60 pts) Use margins to write down your derivations clearly. Problems (i) and (iv) are based on the following description and figure. a b c Atmosphere Pressure = 1.01 bar Oil SG = 0.75 Water Unknown Fluid A C B A U-tube manometer is used to measure the density of an unknown fluid, as schematically shown in the figure on the left. Given: The atmospheric pressure is 1.01 bar. The density of the oil is 0.75 of that of water, i.e., SG = 0.75. Point A is in water; B is at the interface between water and the unknown fluid; C is at the interface between the unknown fluid and air. Given: a = 1 ft, b = 0.9 ft, and c = 1 ft. a b c Atmosphere Pressure = 1.01 bar Oil SG = 0.75 Water Unknown Fluid A C B A U-tube manometer is used to measure the density of an unknown fluid, as schematically...
