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. 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.
