Chapter 9 - Problem 9.E1

Free or natural convection...



Chapter 9 - Problem 9.D1

Again, another typo, the electric resistivity is wrong...



Chapter 9 - Problem 9.C1

We could use this problem as a basis to design lubricants.




Chapter 9 - Problem 9.B1

The heat loss reported in the book is 10 time bigger, I believe this is a typo.





Chapter 9 - Problem 9.A1

A typical heat transfer problem....







Chapter 8 - Problem 8.F2

Molecular diameters!, nice way to measure them!.




Chapter 8 - Problem 8.E2

Thermal conductivity of pure liquids. Beware of the weird energy units, ergs, only physicists and chemists use them.




Chapter 8 - Problem 8.D1

Thermal conductivity of gas mixtures....



Chapter 8 - Problem 8.C1

Thermal conductivity at high pressures...




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.
