Questions 20 to 35 are for Problem 3: Two aligned parallel rectangular plates0.5 mx 10 m. are spaced 0.5 m apart (see Figurel. One plate is mavitained at 1000"C and the other at T - 500°C. The emissivities of the plates are - 0.2 and 10. respectively. The plates are located In a wory large room, the walls of which are maintained at T-27°C and have an amivity of t - 10 The plates exchange heat with each other and the room, but only the surfaces facing each other are to be considered in the analysis Neglect other modes of heat transfer, le conduction and convection Hint this is a three-surface enclosure radiation problem where the room is the third surface Use chart to obtain view factors Stefan-Boltzmann constant e = 5.670 10 Wm.

Two signed parallel rectangular plates. 0.5 mx 10 m, are spaced 0.5 m apart see Figure). One plate is maintained at T- 1000'C and the other at T, - 500'C. The emissivities of the plates are - 0.2 and 2-10 respectively. The plates are located in a very large room, the walls of which are maintained at T - 27" and have an emissivity of t, -1.0. The plates exchange heat with each other and the room. but only the surfaces facing each other are to be considered in the analysis. Neglect other modes of heat transter, ie, conduction and convection. (Hint: this is a three surface enclosure radiation problem where the room is the third surface Use chart to obtain view factors Stefan-Boltzmann constant -5.670 x 10 W.mx 1.0 m - 0.5 m T = 500C =1 Room T, -27C 10 A, 1 0.5 m T, - 1000C 402
