Homework #2 :     

7.5) T = 259^oK, r = 1.36 kg/m³

7.9) r = 0.710 kg/m³,  V = 244 m/sec

8.4) T₀ = 1441^oR, p₀ = 20 atm, T* = 1201^oR, p* = 10.57 atm

8.7) T₂ = 645^oK, p₂ = 7.72 atm, r₂  = 4.2 kg/m³, M₂ = 0.504, T₀₂ = 677^oK, p₀₂ = 9.18 atm

8.10) V₂ = 843 ft/sec, M₂*= 0.5033

8.11) V = 279 m/sec

8.15) T₀ = 1189^oR

1) lower surface: M = 0.777,  V = 899 ft/sec   upper surface: M = 0.755, V = 877 ft/sec
