isentropic efficiency of compression
\[\eta_\mathrm{s} = \frac{h_\text{out} - h_\text{in}}{h\left(p_\text{out}, s_\text{in}\right) - h_\text{in}}\]
components without transfer of work
\[\dot W = 0\]
\[\dot Q = \dot m \left( h_\text{out} - h_\text{in}\right)\]
isenthalpic components
\[\begin{split}\dot Q = 0\\
\dot W = 0\end{split}\]
\[0 = \dot m \left( h_\text{out} - h_\text{in}\right)\]
