Carnot Heat Engine and CyclesCarnot Heat Engine and Cycles
• A Carnot Heat Engine is an idealized heat engine that
operates on the Carnot cycle.
• The Carnot cycle is a theoretical thermodynamic cycle
that consists of four reversible steps: two isothermal
steps and two adiabatic steps.
Carnot Cycle Efficiency and Coefficients of Performance
• The efficiency of a Carnot engine is given by the formula
1 - (Tc/Th), where Tc is the cold temperature and Th is
the hot temperature.
• The coefficient of performance (COP) for a Carnot
refrigerator is given by the formula Th/(Tc-Th), while the
COP for a Carnot heat pump is given by the formula (Th-
Tc)/Tc.
Reversible and Irreversible Processes
• A reversible process is a thermodynamic process that
can be reversed without leaving any traces or changes in
the surroundings.
• An irreversible process, on the other hand, is a process
that cannot be reversed without leaving traces or
changes in the surroundings.
Reversible Heat Transfer and Isothermal Processes
• Reversible heat transfer is the transfer of heat between
two systems at different temperatures in such a way
