1. The problem statement, all variables and given/known data I do not need to solve this problem, see below. EXAMPLE 7.1 Air at a pressure of 6kN/m2 and a temperature of 300C ﬂows with a velocity of 10m/s over a ﬂat plate 0.5m long. Estimate the cooling rate per unit width of the plate needed to maintain it at a surface temperature of 27C. 2. Relevant equations Kinematic viscosity 3. The attempt at a solution My question is about the very first/second step, I have attached pictures showing the example problem and the table A4 from the back of the book. 1. How did they decide on the temperature 437K to use in the table. 2. And why is the viscosity 10^-6? Not 10^6? 3. I see that the description mentions something about the inverse viscosity, can anyone elaborate a little about that? 4.Last question is on the 3rd image it shows the Reynolds number is ~9000, isn't that a turbulent flow, but they say its laminar? According to wikipedia laminar flow is less than 2000 correct? Thanks for any help, I just want to understand the concepts going on. No need to solve the problem.
