Heat engine is a device that converts heat to work .For a specific carnot heat engine which receives heat
at 800 K from hot reservoir and rejects heat at 300K to the cold reservoir.If 60 percent of the the work
output from the heat engine is used as a power input to the carnot refrigerator which removes heat from
cold reservoir of temperature -12 oC at a rate of 500 kJ/minute and rejects the heat to the surroundings
as the heat engine at temperature of 300K.
a. what is rate of heat supplied to the heat engine?
b. What is the total rate of heat rejected to the surroundings?
