5. Consider a hemispherical furnace of diameter 2m with a flat base as shown in the figure below. The dome (surface 1) is black at a temperature of 1000K, and the base has an emissivity of 0.7 at a temperature of 400K. Determine: a. The View factor F11 (5 points) 2 F AGTAG 2 m 01-05-08 b. Evaluate the net radiation heat transfer from the dome to the base during steady operation, in kW (10 points) (1000- Q+123.57kW Pressurized water flowing ot 3 KW
