Carnot's cycle is said to have `25%` efficiency when it operates between `T` (source) and `300K` (sink). Temperature `T` is

Efficiency of carnot heat engine,if source temperature is T1K and sink temperature is T2K

The efficiency of Carnot engine when source temperature is T 1 and sink temperature is T 2 will be

A Carnot engine has efficiency 25%. It operates between reservoirs of constant temperatuers with temperature difference of 80^@C . What is the temperature of the low -temperature reservoir ?

A Carnot engine has efficiency 25%. It operates between reservoirs of constant temperatuers with temperature difference of 80^@C . What is the temperature of the low -temperature reservoir ?

A Carnot engine of efficiency 40% , takes heat from a source maintained at a temperature of 500 K . If is desired to have an engine of efficiency 60% . Then , the source temperature for the same sink temperature must be

A carnot engine has the same efficiency (i) between 100K and 500K and (ii) between TK and 900K . Caculate the temperature T of the sink.

The efficiency of a Carnot engine which operates between the two temperatures T_1=500K and T_2=300K is
