Question

jet has to fly at speed of 400 m/s at a height of 10000 m above sea level (T = – 45 C and P = 0.2981 atm). For testing in a pressurized wind tunnel at 15 C, A 1:20 model is designed. For complete dynamic similarity what pressure and velocity be used in the tunnel

Answer 1

Answer:

Fluid Mechanics

If model and prototype satisfy dynamic similarity, what prototype velocity ... Solution: For water at 20°C take ρ ≈ 998 kg/m3 and µ ≈ 0.001 kg/m⋅s.
