Isentropic Flow Equations (868 words) |
 | Isentropic flows occur when the change in flow variables is small and gradual, such as the ideal flow through the nozzle shown above. |
| We call this an isentropic expansion because of the area increase. |
| The isentropic relations are no longer valid and the flow is governed by the oblique or normal shock relations. |
| ISENTROPIC LIFTING (423 words) |
| The idea of isentropic lifting is air "prefers" to move toward air with the same density. |
| The uplift is at a lower angle than uplift that is generally associated with cold fronts and thermodynamic thunderstorms. |
| Answer: It is because isentropic lifting does not occur on a constant pressure surface. |
