Why is the compression considered as isentropic in Otto cycle? | pressku.com

Trending 4 months ago

We cognize nan perfect Otto rhythm is modeled by nan 2 perfect processes isentropic (compression and description ) and isochoric (heat summation and power rejection). But why nan compression and description process is considered arsenic isentropic ? It should beryllium nan Adiabatic process arsenic location is nary capable clip to speech nan power to nan surrounding arsenic compared to nan velocity of piston. Also, T*dS >= dQ From here, yes we do get dS >= 0. But really tin we reason location is nary entropy change.

Is location immoderate reference explaining really is nan existent rhythm is modeled to make it ideal. How is nan process modeled ?
