The electric reheating oven is used to heat a continuous sheet of metal from 25-1000C The metal speed is such that the strip of metal spends 2 hours inside this oven, The sheet thickness is 1cm and the ambient temperature is 25C with the temperature of the outside of the oven a uniform 50C. Inside the oven use a h_convection= 20 W/ m^2*K and the metal sheet is 304 ss. Calculate the electric power input to the oven per unit oven width; q'. What percentage of this power is lost by convection to the outside air?
