| The first and third legs are nearly isothermal, while the second and fourth legs are nearly isentropic. |
| Because there is no heat flow, the entropy remains unchanged according to the second law of thermodynamics, so the adiabatic process is also isentropic. |
| Capacities are based on 38°C condensing temperature isentropic compression plus 28°C, evaporator temperature as shown plus 14°C superheat suction gas. |
| Other inputs included the degree of superheat and subcooling, isentropic efficiency of the compressor etc. |
| David Scarborough, a senior research engineer, teaches the jet and rocket propulsion class, full of terms like isentropic flow and stagnation states as well as adiabatic efficiency for the diffuser. |
| Because air particles tend to flow along isentropic surfaces rather than at constant levels, the life history of air currents can be conveniently followed from day to day by means of isentropic charts. |
