... condensation in Section 8.5, and of pool boiling burnout in Section 9.3. In all of these cases, heat transfer normally occurs without any conversion of heat to work or work to heat and it would be misleading ... T  = dT/dt and X  = d 2 X/dx 2 . Rearranging eqn. (4.6), we get X  X = 1 α T  T (4.7a) This is an interesting result in that the left-hand side depends only upon x...
