Information
This example illustrates the influence of the ambient pressure on the power (net expansion work flow rate) of a periodic isobaric closed-cycle process.
For p = p_inf, the net power is zero.
For p \gt; p_inf the net power is directed out of the system in case of a temperature increase (expansion) and into the system for a temperature decrease (compression).
For p \lt; p_inf the net power is directed into of the system in case of a temperature increase (expansion) and out of the system for a temperature decrease (compression).
