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 71.2 63.8 48.7 77.2 71.2 63.8 48.7 77.2 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Fresh orange juice contains 12% (by weight) solids and the rest water 90% of the fresh juice is sent to an evaporator to remove water and subsequently mixed with the remaining 10% of fresh juice. The resultant product contains 40% solids. The kg of water removed from 1 kg fresh juice is 0.7 0.5 0.6 0.4 0.7 0.5 0.6 0.4 ANSWER DOWNLOAD EXAMIANS APP
