## Description

Basic Heat Transfer aims to help readers use a computer to solve heat transfer problems and to promote greater understanding by changing data values and observing the effects, which are necessary in design and optimization calculations.

The book is concerned with applications including insulation and heating in buildings and pipes, temperature distributions in solids for steady state and transient conditions, the determination of surface heat transfer coefficients for convection in various situations, radiation heat transfer in grey body problems, the use of finned surfaces, and simple heat exchanger design calculations. The text also includes a review of the BASIC computing required and some mathematical programs to solve heat transfer problems.

The book will be useful to mechanical engineers, students of engineering, and designers.
