Carnot engine operates between source temperature of 500 K and sink temperature of 300 K. It produces work utilizing the heat of k from the source at 500 K. The work produced by this engine is utilized by a Carnot refrigerator operating between refrigerator temperature of 200 K and sink temperature of 300 K. Represent schematically these engine and refrigerator operations.
Find out :
- Work produced by the Carnot engine.
- Refrigerating effect produced at 200 K by the Carnot refrigerator.
- Total heat rejected to the sink at 300 K.
- By how much the refrigerator temperature be increased to get double the refrigerating effect as per (ii) above?
- Total heat rejected to the sink at 300 K when the refrigerator operates as per the temperature for (iv) above.
