Multiple choice

For the three dimensional object shown in the figure below, five faces are insulated. The sixth face (PQRS), which is not insulated, interacts thermally with the ambient, with a convective heat transfer coefficient of 10 W/m2.k The ambient temperature is 30oC. Heat is uniformly generated inside the object at the rate of 100 W/m3. Assuming the face PQRS to be at uniform temperature, its steady state temperature is

  1. 10oC

  2. 20oC

  3. 30oC

  4. 40oC
