A closed chamber containing a gas is at steady state. The shaft transfers power at a rate of 2 kW to the paddle wheel and the electric lamp consumes electricity at a rate of 500 W. Using an energy balance determine
(a) The rate of heat transfer.
(b) If the surface temperature of the chamber is 400 K, determine the entropy generated within the chamber.
(c) What-if Scenario: What would the entropy generation within the chamber be if the surface temperature increased to 500 K?
