Alright... why are these solutions written so in a way that give only partial explanations. I'd rather have 1/8th of the practice problems if I had complete solutions where the logic could be traced step by step. For instance, problem 14-2 of the 12th edition practice problems. Need to calculate kinematic viscosity. No problem. A quick look in MERM index gives formula for KV. Need absolute viscosity for air at a certain temperature and pressure. No problem, I'll look it up in MERM. What? It's not in there? Stumped. Look at solution. Solution says "For air at 14.7 psia and 80F, the absolute voscosity independent of pressure = 3.85E-7 lbf-sec/ft^2."
Am I just supposed to log that into my memory? What if they ask about a different fluid on the test? I can't find anything providing help in MERM on figuring or looking up absolute viscosity???
