A Circular Ice Rink Is 20 M In Diameter. The Ice Rink Is Enclosed In A Hemispherical Dome Of The Same Diameter. The Ice Is Maintained At - 3 Degree C (270 K). The Inner Surface Of The Dome Is Measured To Be + 77 Degree C (290 K). Calculate The Radiant Heat Transfer From The Dome To The Rink. Assume That Both Surfaces Can Be Taken As Black.

 

 

 

Problem 3 (35 points) A circular ice rink is 20 m in diameter. The ice rink is enclosed in a hemispherical dome of the same diameter. The ice is maintained at -3C (270 K). The inner surface of the dome is measured to be +17C (290 K). Calculate the radiant heat transfer from the dome to the rink. Assume that both surfaces can be taken as black. T-270 K 71-290 K Az 10 m A
