WebStagnation pressure jump relation The stagnation pressure ratio across the shock is po2 po1 = p2 p1 1 + γ−1 2 M2 2 1 + γ−1 2 M2 1!γ/(γ−1) (1) where both p2/p1 and M2 are … WebAug 12, 2024 · 1. If the total temperature increased, energy would need to have been added to the flow via work or heat transfer. A change in stagnation temperature is directly related to work being taken or added to the flow (see energy equation/Euler work equation). Since the stator does not put work into the flow or extract work out, the total temperature ...
