A flaked cereal is of thickness 2L = 1.4 mm. The density,specific heat, and thermal conductivity of the flake a rep=700 kg/m', , = 2400 J/kg · K, and k

= 0.34 W/m K,respectively. The product is to be baked by increasing its temperature from T; = 20°C to T = 220°C in a convection oven, through which the product is carried on a conveyor. If the oven is L, = 3 m long and the convection heat transfer coefficient at the product surface and oven air temperature are h =respectively, determine the required conveyor velocity, V.An engineer suggests that if the flake thickness is reduced to 2L = 1.0 mm the conveyor velocity can be increased,resulting in higher productivity. Determine the required conveyor velocity for the thinner flake
