Heat Transfer - Engineering

Q1:

Heat transfer by radiation between two bodies at T1 & T2 and in an ambient temperature of Ta°C depends on

A T1 - T2

B T1 - Ta

C T2 - Ta

D none of these

ANS:D - none of these

The rate of heat transfer by radiation between two bodies at temperatures T1 and T2, respectively, and with an ambient temperature of Ta°C, depends on the temperature difference between the bodies and the surroundings. Therefore, the correct option is: T1 - Ta
