Problem 3.1b Hint

In part b, define an intermediate temperature, T_m, as the temperature at the interface between the slabs. The heat flow at this contact point must be unique - no matter how you calculated it.

Problem 3.6 Hint

Assume no breeze is blowing - what does this imply about convection? Estimate alpha as 0.9. Why don't you need to know the size of the space ship? New Hint - due to the somewhat confusing language of Example 3.1, "still air" in convection I will just state that you should use heat flow by only radiation and conduction in this problem.

Problem 3.7 Hint

As I mentioned in class, use the simple solid equation of state for water.

Problem 3.13 Hint

This is a long problem!

Problem 3.15 Hint

Use the matlab function fzero to do the numerical part of this problem. Type "help fzero" for instructions. You will need to write a Matlab function to solve this problem. Type "help function" to see the syntax for Matlab user-defined functions. You must save your function definition to a file ending in .m in the directory you are running Matlab in.
