A rolled oat's piece has a thickness =1.2 mm. The density= 600 kg/m3, specific heat capacity=2200 J/kgK and thermal conductivity= 0.4 W/mK,The product is to be baked from twenty degree celsius to 200 degree celsius in an oven on a conveyor belt. The distance along the conveyor belt is four meters. The prevailing convective heat transfer coefficient = 60W/m2K and the oven air temperature = 350°C.Determine the velocity of the conveyor belt.
