Question 1 (CLO 1, PLO 2, C3): A flat plate with a surface area of 0.25 m moves above a parallel flat surface with a lubricant film of thickness 1.5 mm in between the two parallel surfaces. If the viscosity of the lubricant is 0.5 Pa-s, analyze the following: a. Damping constant b. Damping force developed when the plate moves with a velocity of 2 m/s. Question 2 (CLO 1, PLO 2, C3): A machine is subjected to the motion...
Start by checking your Reynolds number (Re) at the end of the plate, where it will be at a maximum. This will determine if your boundary layer is simply laminar along the length of the plate or if it becomes turbulent (the "mixed BL" condition). Once you know the conditions of the flow, you can solve for the velocity BL thickness directly with an equation from the list of external flow correlations (posted). Your properties should be looked up at...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
