Heat Transfer The left face of a one dimensional slab of thickness 0.2 m is maintained at 80°C and the right face is exposed to air at 30°C. The thermal conductivity of the slab is 1.2 W/m.K and the heat transfer co-efficient from the right face is 10 W/m².K. At steady state, the temperature of the right face in °C is 77.2 63.8 71.2 48.7 77.2 63.8 71.2 48.7 ANSWER DOWNLOAD EXAMIANS APP
