WebReversible processes are useful in thermodynamics because they are so idealized that the equations for heat and expansion/compression work are simple. This enables the … Webwork to real work: ηs = τs τ = hs - ha hr - ha (4.1.7) This efficiency measures the imperfection of the process from the reversible adiabatic. It is important to note that the adiabatic efficiency ηs is thus the main characteristic of an irreversible adiabatic process, but its determination also presents the greatest difficulties.
