Answer is:
between the second heat exchanger and the cooling turbine
Answer is:
fourth power of the absolute temperature
Explanation:
According to Stefan's law, the total radiation from a black body per second per unit area is directly proportional to the fourth power of the absolute temperature. Stefan Boltzmann law is applicable for heat transfer by radiation. The unit of Stefan-Boltzman is Watt/m2K4.
