Example 22.2. A thin slab of meat is to be cooled from 34°C to a temperature of 5°C with the help of a cooling medium at a temperature of 2°C. Determine the time required at the centre of a thin slab when the slab is 120 mm thick and to be cooled from both the sides. Following are the heat properties of the slab material : k = 0.6 W/m K; c, = 3.65 kJ/kg K; p= 1040 kg / m'; f, = 20 W/m %3D
