Two coaxial cylinders of radii 2 cm and 8 cm are held at 100°C and 20°C with a uniform conducting substance between them. Find the temperature at a radius of 4 cm, in °C.

Answer:

Solution:

$T = T_{1} + \frac{T _{2} - T _{1}}{ln ( R _{2} / R _{1} )} ln \frac{r}{R _{1}} = 100 - 80 \times \frac{ln 2}{ln 4} = 100 - 40 = 6 0^{\circ}$ C.
