Which efficiency cost results when friction increases inside a Carnot engine?

💡 Explanation

Increasing friction in the engine causes more energy to be dissipated as heat which then results in increased entropy, because friction introduces irreversibilities that remove energy from the system. Therefore entropy generation increases, rather than the transfers maintaining equilibrium, while isothermal and adiabatic processes suffer.
