Chapter 8 - Problem 8.B1
The Prandtl number is essential for the estimation of heat transfer coefficients.
Chapter 8 - Problem 8.A1
The problem illustrates a way to predict thermal conductivities based on the Chapman-Enskog theory. However, engineers use polynomial regressions based on experimental data.

Chapter 6 - Problem 6.L2
This problem iluustrates the error obtained by using the concept of hydraulic radius for laminar flow.
Chapter 6 - Problem 6.K2
This is a very interesting problem. Just take a good look at the derivation of the Reynold's number for a non-newtonian fluid that can be modeled with the power law approach.
Chapter 6 - Problem 6.J2
This problem illustrates the derivation of a correlation to determine the friction factor based on Reynolds number for smooth pipes. However, pipes are not 100% smooth...
Chapter 6 - Problem 6.H2
With this problem, we derive expressions to determine the friction factor for a rotating disk. I believe this can be applied for the study of rotating equipment.
