A 25 mm diameter egg roll (k = 1 W/m degree) is roasted with the help of microwave heating. For good quality roasting, it is desired that temperature at the center of roll is maintained at 100 degree Celsius when the surrounding temperature is 25 degree Celsius. What should be the heating capacity in W/m of the microwave if the heat transfer coefficient on the surface of egg roll is 20 W/m degree? a)613.31 k W/m b) 93.31 k W/m c) 6713.31 k W/m d) 213.31 k W/m 3
