Heat Transfer - Engineering
Q1: 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 isA 77.2
B 71.2
C 63.8
D 48.7
ANS:D - 48.7 To solve this problem, we can apply the steady-state heat conduction equation for a one-dimensional slab: Q=Lk⋅A⋅(T1−T2) Where:
