A Carnot engine has the same efficiency
between 100 k and 500 k .Calculate the temperature T K & 900 K of the sink.

A Carnot engine has the same efficiency between 800 K to 500K to 600K . The value of x is

A Carnot engine, whose efficiency is 40% , takes in heat from a source maintained at a temperature of 500K. It is desired to have an engine of efficiency 60% . Then, the intake temperature for the same exhaust (sink) temperature must be:

A reversible engine converts one fifth of heat which it absorbs from source into work. When the temperature of the sink is reduced by 70^@ , its efficiency is doubled. Calculate the temperature of the source and the sink .

A Carnot refrigerator operates between 250^@K and 300^@ K . Calculate its coefficient of performance .

Relation between K_C and K_p- .

A Carnot refrigerator operates between 250^@K and 300^@K . Calculate its coefficient of performance.

Mean kinetic energy of a perfect gas per gram at the temperature T^@K is

Heat engine takes 300 cal of heat 500 K and rejects 150 cal of heat to sink. The temperature of sink is

200cal of heat is given to a heat engine so that it rejects 150 cal of heat, if source temperature is 400 K then the sink temperature is

A Carnot engine whose low temperature reservoir is at 7^@C has an efficiency of 40. It is desired to increase the efficiency to 50% . By how many degree must the temperature of the high temperature reservoir be increased?
