A stainless-steel plate having thickness 0.005 m, area 1.75 m^2, thermal conductivity 16 W/m·K and emissivity 0.4 is being heated by?

Update:

A stainless-steel plate having thickness 0.005 m, area 1.75 m^2, thermal conductivity 16 W/m·K and emissivity 0.4 is being heated by electrical heater. At steady state the temperature of a heated surface of a plate is 265 °C and heater draws 200 V and 27 A. A back-side surface of a plate is being cooled by air with a temperature of 20 °C. Determine a convective heat transfer coefficient on the cooled surface.
