Consider a cylindrical cavity of diameter D = 100 mm and depth L = 60 mm whose sidewall and bottom are diffuse and gray with an emissivity of 0.6 and are at a uniform temperature of 1500 K. The top of the cavity is open and exposed to surroundings that are large and at 300 K (a) Calculate the net radiation heat transfer rate from the cavity, in W, treating the bottom and sidewall of the cavity as one surface. (b) Calculate the net radiation heat transfer rate from the cavity, in W, treating the bottom and sidewall of the cavity as two separate surfaces. Part A * Your answer is incorrect. Calculate the net radiation heat transfer rate from the cavity, in W, treating the bottom and sidewall of the cavity as one surface. 91 = i 115 W
