7.1 INTRODUCTION

This chapter deals with different modes of heat transfer, which are usually classified as conduction, convection, and radiation. From the second law of thermodynamics, we know that the heat flows whenever there is existence of temperature difference or temperature gradient. Heat is a form of energy which is transferred from one body to another body at a lower temperature, by virtue of the temperature difference ...
