Calculate the net radiant-heat-transfer rate if the two surfaces in Problem 9.10 are black and connected by a refractory surface of 500-sq-m area. A1 is at 555 K and A2 is at 278 K. What is the refractory surface temperature?From Problem 9.10: Derive an expression for the geometric shape factor F1??2 for a rectangular surface A1. 1 by 20 m placed parallel to and centered 5 m above a 20-msquare surface A2.GIVENRectangular surfaces A1 and A2 connected by a refractory surface A3A1 is parallel to and centered 5 m above A2Dimensions of A1 = 1m x 20 mA2 is 20 m2A3 is 500 m2Temperature of A1 (T1) = 555 KTemperature of A2 (T2) = 278 KA1 and A2 areblack

A1 :1 mx 20 m = 20 m? T1= 555 K End View : Ag = 500 m2 Az: 20m x 20 m = 400 m? T2 = 278 K
