Why Carnot cycle is impractical? Carnot cycle is impractical because its two processes isothermal expansion and isothermal compression involve transfer of heat and work simultaneously. But most equipment separate processes involving heat from those involving work. Turbines and compressors involve work but are typically nearly adiabatic. Heat exchangers involve heat transfer but do not involve work transfer. The reason for these processes are separated in practical components is related to large amount of time that is required for fluid to transfer heat compared to short amount of time that is required for fluid to transfer work.
