Now that we are all wrapped up in semantics... [img]/ubbthreads/images/graemlins/tongue.gif[/img] Ron, what you were looking for is the isentropic efficiency. The conditions for an isentropic process (well insulated and reversible) are somewhat more restrictive than those for an adiabatic process (well insulated). Isentropic processes are by definition adiabatic. Anyway, I knew what you were talking about.

Well you asked for it, here are both barrels.
