A plate (Z +0.4) m long and (Z + 0.15) m wide, with a thickness of (Z+ 15) mm is made from stainless steel (k = 16 W/mK). The temperature at the bottom surface of the plate is 100 °C maintained by an electrical heater supplied by 250 v and 0.45 A. In a steady-state condition, assuming that the plate is perfectly insulated on all sides except top surface, find temperature at the top surface of the plate.
