diation, convection and conduction 1 1 A F12 (1-12) W Ah 1 A1F12T2 N 3 At the oven door given in Example 8.14, the convection coefficient on the inside surface of the door (oven side) is 20 W/m2-K; on the outer side is 10 W/m2-K, the thickness of the glass 8 mm and conductive heat transfer coefficient of the glass is 1 W/mK. Draw the radiative network and determine; Heat loss from the oven and the temperature on the outer surface of the glass. 1 Azha Azaz (1-T) 2L 24 2R Pz 8242(1-12) t KA P2 24(1-12) Furnace Window Room Hint: Eb1 = Eb + Eb1b, Eb2L = Eb2La + Eb2Lb, Eb2R = ; T2L (Eb2L/o)1/4, ... First of all, estimate T2L and T2R, and EbLa, Eb2Lb, Eb2Ra, Eb2Rb at this surfaces, and after the calculations, determine these temperatures again and repeat the process.
