Work done by Carnot engine whose heat accepted 5000Kcal from `727^@C` and given to `127^@C`.

If a Carnot engine works between 127^@C and 727^@C , then its efficiency is

A Carnot engine takes 9000 cal of heat from a reservoir at 627^@ C and gives it to a sink at 27^@C . The work done by the angine is

If the work done by a Carnot engine working between two temperatures 600K & 300K is used as the work input in Carnot refrigerator, working between 200K & 400K, find the heat (in J) removed from the lower temperature by refrigerator? The heat supplied to engine in 500J

A carnot engine takes in 3000 kcal of heat from a reservoir at 627^@C and gives a part of it to a sink at 27^@C . The work done by the engine is

A carnot engine takes 6000 cal of heat from a reservoir at 627^(@)C and gives it to a sink at 27^(@)C . The work done by the engine is

If a Carnot’s engine functions at source temperature 127^(@)C and at sink temperature 87^(@)C , what is its efficiency

A perfect carnot engine has source temp. 227^(@)C and sink temp. 127^(@)C . Find the efficiency of the engine, If 10000J of external work is to be done, find heat received from source and heat released to the sink.

If a carnot engine works between 127^(@)C and 527^(@)C then its efficiency is
