Chapter 10, Problem 10.14P

(a)

Interpretation Introduction

Interpretation:

The time required to achieve centerline temperature is to be determined.

Concept Introduction :

Based on the fundamentals of unsteady-state heat transfer and its general solution for conduction in infinite slab depends on not only temperature conditions but also the dimensional specifications and physical properties of the material. This means that the heating or cooling time and the temperature limit would also be affected by such properties.

(b)

Interpretation Introduction

Interpretation:

The average temperature achievable in pre-determined heating or cooling time is to be determined.
