A hot plate of area 0.2 m² is maintained at a temperature of 59°C by a 100 W heater when the room temperature is 20°C. The appropriate convection coefficient is 2.512 (AT)¹/4 W/m² K. Taking heat transfer from plate is by convection and radiation, the percentage of heat lost by radiation is (a) 27 (b) 49 (c) 51 (d) 56 A hot plate of area 0.2 m² is maintained at a temperature of 59°C by a 100 W heater when the room temperature is 20°C.
