The efficiency of a Carnot heat engine

(A): Efficiency of carnot engine increase on reducing the temperature of sink. (R ): The efficiency of a Carnot engine is defined as ratio of net mechanical work done per cycle by the gas to the amount of heat energy absorbed per cycle from the source.

Heat engine rejects some heat to the sink. This heat

The efficiency of Carnot heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) . The efficiency of another Carnot's heat engine is also 0.5 . The temperature of source and sink of the second engine are respectively

The efficiency of Carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) . The efficiency of another Carnot's heat engine is also 0.5 Then temperature of source and sink of the second engine are respectively

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 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

The efficiency of a carnot engine eta = 1/10 . This carnot engine used as refrigerator. If work done on system is 10 J, then heat absorbed from sink will be …….
