To control the temperature and drying rate of bread, a humidified baking oven is maintained at 166°C dry bulb and 60°C wet bulb temperatures. The walls of the oven radiate heat as black bodies. The air is circulated in the oven by natural convection so that the heat-transfer coefficient is given by = 1.974 (t-ts0.25 The oven is 0.3 m cube and the bread-pan dimensions are 0.3 m x0.1 m x0.1 m. Determine the drying rate during the constant-rate drying period. Neglect drying from the base of the pan.
