Rayleigh supersonic pitot equation
WebThe Pitot pressure P p, can be used to nd a value for the local Mach number M 1 using a similar process developed for pure air jets. Wherever the ow is supersonic, a shock forms in front of the probe, and P p is equal to the total pressure behind the shock, P t2. M 1 is then calculated using the Rayleigh Pitot formula shown in Eq. WebIn the first half of this paper, we present a fresh perspective toward the Wind Triangle Problem in aerial navigation by deriving necessary and sufficient conditions, which we call …
