. A cylindrical rod has a length of 30 cm and a diameter of 2.4 cm. One end is kept in a fire at 500◦C while the other is held in cool water kept at 14◦C. What is the rate of heat conduction across the rod?
Conductive heat transfer can be expressed with Fourier's Law:
q = k A dT / s
where
q = heat transfer
A = heat transfer area
k = thermal conductivity of the material
dT = temperature gradient - difference - in the material
s = material thickness
Here A= 3.14*0.012*0.012=4.52*10^-4 m^2
d=0.3m
dT=486
Considering the rod is of iron, k=80
So q=80*4.52*10^-4*486/0.3
So q=58.57 W
