Aerospace Engineering > GATE 2017 > Normal Shock Waves
A strong normal shock wave, with a pressure ratio of 29 across it, is travelling into stationary air (γ=1.4) at T=280 K in a straight duct (see figure). The magnitude of the velocity of the air induced behind the shock wave is _______ m/s. (round to nearest integer)
(Gas constant =287 J/kg.K Shock wave relations:
Pressure ratio: p2/p1=1+(2γ/(γ+1))(M2-1); Density ratio: ρ2/ρ1=((y+1)M2)/((y-1)M2+2)
(Gas constant =287 J/kg.K Shock wave relations:
Pressure ratio: p2/p1=1+(2γ/(γ+1))(M2-1); Density ratio: ρ2/ρ1=((y+1)M2)/((y-1)M2+2)
Correct : 1341 to 1343
