Q.3- A solid cylindrical bar which has 150 mm diameter and 220 cm long is located vertically in 20 °C quiescent air. Its surface temperature is maintained at 120 °C and total heat transferred is 1500 W from this bar to the ambient air. Calculate emissivity value of the bar surface. Neglect heat transfer from upper and lower cross-sectional surfaces of the bar.
