Solve the following problem:
Q: Use a flux plot to estimate the rate of heat flow through the object shown in the sketch. The thermal conductivity of the material is 15 W/(m K). Assume no heat is lost from the sides.
GIVEN
The shape of object shown in the sketch
The thermal conductivity of the material (k) = 15 W/(m K)
The temperatures at the upper and lower surfaces (30°C & 10°C)
ASSUMPTIONS
No heat is lost from the sides and ends
Uniform thermal conductivity
Two dimensional conduction
Steadystate
