WebThere is one problem involving an isothermal (as opposed to adiabatic) air compressor. The idea here is to cool the air (i.e., remove heat) as it is compressed. When the process is assumed to be reversible and isothermal, the heat transfer in the process can be predicted from application of the second law. On a per-unit-mass basis, q = T(s2 s1) WebThe entropy of a given mass does not change during a process that is internally reversible and adiabatic. A process during which the entropy remains constant is called an isentropic process, written = or =. Some examples of theoretically isentropic thermodynamic devices are pumps, gas compressors, turbines, nozzles, and diffusers.. Isentropic efficiencies of …
