# Question: the area of the heat flow can change as in...

###### Question details

The area of the heat flow can change as in the case of a cylinder or a sphere. With that in mind, solve the heat transfer problem for a 4 cm-high truncated cone. Its base diameter is 8 cm and the top diameter is 4 cm. The sides are insulated and the base and top temperatures are 80 and 40oC, respectively. Assuming this is a 1D heat flow, estimate the heat flow. The cone material has a thermal conductivity of 10 W/m K.
