Metallurgical Engineering > GATE 2025 > Radiation Heat Transfer
Radiative heat flux ˙q at a hot surface at a temperature Ts can be expressed as ˙q=A f(Ts,T∞)(Ts-T∞), where A is a constant and T∞ is the temperature of the surroundings (temperatures are expressed in K).
The function f(Ts,T∞) is given by
A
(Ts+T∞)2(Ts-T∞)
B
(Ts2+T∞2)(Ts+T∞)
C
(Ts2-T∞2)(Ts+T∞)
D
(Ts-T∞)2(Ts+T∞)

Correct : b
