TUT#04 - Vraag / Question 07
'n Konvergerende-divergerende mondstuk het 'n keel area van 10 [cm²] en 'n uitlaat area
van 20 [cm²]. Lug word voorsien vanaf 'n lug tenk met 250 [kPa] en 350 [K]. By 'n regte
kondisies die uitlaat kondisies is P. = 183 [kPa], T₁ = 340 [K] and V₂ = 144 [m/s].
e
1) Is daar 'n normaal skok in die mondstuk? Motiveer
2) Indien Ja, by watter Mach getal sal die normaal skok gebeur?
