HEAT TRANSFER PROBLEM NO18 - The configuration of a furnace can be approximate as an equilibrium triangular duct which is usually long enough so that the end effects are negligible , the hot wall is maintained at 900 k and has an emissivity e1 = 0.8 . The cold wall is at 400 k and has an emissivity , e2 =0.8 .The third wall is re-radiating zone. What is the net radiation heat flux leaving the hot wall ?
Discuss the applicability of each model - Does it differ based on the interactions you would expect for each model. Can you conclude that one of the models is 'better' than the others from your graphs/analysis in Problems 3.1-2?
In Addition, Iodine-131 is used in the diagnosis and treatment of thyroid disease and has a half-life of 8.1 days. If a patient with thyroid disease consumes a sample of Na131I containing 10 of 131I, how long will it take for the amount of 131I to..
