But in this case all isentropic curves, if sufficiently prolonged, will enter the heterogeneous region. |
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. |
The flow of air at the isentropic surface is represented by streamlines, computed from the field of pressure and temperature. |
How do I choose between polytropic efficiency and isentropic efficiency? |
The isentropic surface varies in height from place to place over the Earth, the variation being indicated on the isentropic chart by isobars, lines showing the pressure at which the isentropic surface is found. |
In the same way the critical point of the isentropic curves comes nearer to that of the isothermals. |
