Speed of Sound Corresponding with Stagnation Temperature (3.2.3) a = NYRT Critical Speed (3.2.4) M=1 Va NORTH = N2 FIR(ToT) 2 Tce (To-Tee) 2 ACR NOR TO +1 Ex. Rank the velocities: Vmax a. ack N = 2 Vmax YRTE TRE > Number (3.2.5) Mach number has two issues: 1) when v varied, then a varied with T and hence v 2) If v increases a lot then M00 So & fixes these: v² az a ace M2. a I M² TR ho-hav² ToT +2 ht ToT+2Cp T(1+20PT)- TCI+ )→ To T I x²=M²=M²x²-M²(1+2) TOR To 2 How does 2 vary with M?
