Conduction Heat Transfer 1. Write a summary of second chapter equations. 2. Explain the different thermal resistances in parallel planes, cylinder, and spheres. How to get the total resistance values if three resistances are in series or in parallel. Explain the difference between radiation heat transfer coefficient, overall heat transfer coefficient and combined heat transfer coefficient. 3. Explain the concept of critical thickness of insulation in cylinderical and spherical co-ordinates. 4. Define and differentiate fin efficiency and effectivenss. Explain the non-dimensional temperature ratio, heat transfer, fin efficiency, and effectiveness for long and adiabatic tip fins separately. 5. How to choose sink for electronic devices 6. Explain the shape factor in 3 dimensional heat conduction problems with example. 7. Solve any 5 numericals related to this chapter.

I want a solution for each question step by step. And as soon as possible
