At the nozzle of the plane, the temperature is at 400°K at a velocity of 450 m/s. Is the plane at subsonic? Sonic? Supersonic? Or Hypersonic? Show your computations. MACH number, Ma: U TYPES of compressible flow: (a) Subsonic - Ma < 1 (b) Sonic - Ma ≈ 1 Ma = Speed of fluid = u (c) Supersonic - Ma> 1 Speed of sound = a yP YTR a = Where: T = absolute temperature P = pressure M = molecular weight of fluid y = specific heat ratio (Cp/Cv) Cp = Cp-R/M pu² u²M Therefore: Ma² = = YP YTR --
