Question

define correlation of thermal conductivity​

Answer 1

Answer:

Coefficient of thermal conductivity - definition. Coefficient of thermal conductivity:=A(θ2−θ1)tQd. Cefficient of thermal conductivity of the material of solid is equal to the rate of flow heat per unit area per unit temperature gradient across the solid.

Answer 2

PROPORTIONALITY OF RATE OF HEAT TRANSFER AND TEMPERATURE GRADIENT AT STEADY STATE - DEFINITION

In steady state, the rate of flow of heat H from one point to another is proportional to the temperature difference (T1−T2) and the area of cross section A and is inversely proportional to length L:

H=KALT1−T2

The constant of proportionality Kis the thermal conductivity of the material.

COEFFICIENT OF THERMAL CONDUCTIVITY - DEFINITION

Coefficient of thermal conductivity:=A(θ2−θ1)tQd

Cefficient of thermal conductivity of the material of solid is equal to the rate of flow heat per unit area per unit temperature gradient across the solid.
