Question

Emma is on a space mission to Jupiter. Her spaceship is equipped with nuclear powered engine with large radiators. The radiators keep the hot reservoir at a max temperature of 750 K while the cold reservoir is water running at normal room temperature. What is the max theoretical efficiency of the spaceship? Why does she need the radiators if deep space is very cold?

Answer 1

Theoretical efficiency,

The radiators are needed to keep the temperature in a specified range to extract the optimal performance from various equipment onboard and for comfortable living of humans inside it.
