In a given engineering application, the relationship between the body's temperature

In a given engineering application, the relationship between the body's temperature and its surrondings is descrifollows; =1- [Tx5.455 x104) The body's temperature is 1100 C and the surroundings being 550 C. Assuming that this body is in black surrounding; (i) Calculate the net heat loss by radiation by assuming the body to be grey [5 marks] (ii) Calculate the net heat loss by radiation by assuming the body NOT to be grey [5 marks]
