+ Eg - [h(T - Too) + - = (5.15) Use the above equation with E_gen= 0 to solver 5.11 The base plate of an iron has a thickness of L = 7 mm and is made from an aluminum alloy (p = 2800kg/m³, c = 900 J/kg K, k = 180 W/m- K, s = 0.80). An electric resistance heater is attached to the inner surface of the plate, while the outer surface is exposed to ambient air and large surroundings at Two = Thu = 25°C. The areas of both the inner and outer surfaces are A, = 0.040 m². Surroundings. Thur Air T_.. h Baseplate (p. k. 2, q%. 1, A,) If an approximately uniform heat flux of d'e = 1.25 X 104 W/m² is applied to the inner surface of the base plate and the convection coefficient at the outer surface is h = 10 W/m2.1 K, estimate the time required for the plate to reach a temperature of 135°C. Hint: Numerical integration is suggested in order to solve the problem.
