An enclosure measures 1.5 m × 1.7 m with a height of 2 m. The walls and ceiling are maintained at 250°C and the floor at 130°C. The walls and celling have an emissivity of 0.82 and the floor 0.7. Determine the net radiation to the floor (in kW).
Enter numerical value using the virtual keypad. Round off where necessary.
