Question

Consider a hemispherical furnace of diameter D=6m with a flat base. The dome of the furnace has an emissivity of 0.7 and the flat base is a blackbody. The base and the dome are maintained at uniform temperature of 300K and 1200K, respectively. Under steady state conditions, the rate of radiation heat transfer from the dome to the base is _____kW (rounded off to the nearest integer).
Use Stefan-Boltzmann constant = 5.67×10-8 W/(m2K4)

Answer 1

The correct answer is:2720 to 2740
