Q143
Fourier's law of heat conduction gives the heat flow for
A.
Irregular surfaces
B.
Nonuniform temperature surfaces
C.
One dimensional cases only
AnswerD.
Two dimensional cases only
Answer: Option C
Solution
Answer: Option C
Solution:
Fourier's law of heat conduction is valid for One dimensional cases only
Fourier equation is valid for all matter solid, liquid or gas. The vector expression indicating that heat flow rate is normal to an isotherm and is in the direction of decreasing temperature.
