![Q.10. To predict the drag on an aircraft at a flight speed of 150 m/s, where
the condition of air is such that the local speed of sound is 310 m/s, a
pressurized low temperature tunnel is used. Density, viscosity and local
sonic velocity at tunnel condition are 7.5 kg/m³, 1.22 x 10-5 Ns/m² and 290
m/s. Determine the flow velocity and the scale of the model. Assume full
dynamic similarity should be maintained. Density and viscosity at the
operating conditions are 1.2 kg/m³ and 1.8 x 10 Ns/m².](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0caba90-13db-4eb3-b141-069db120e33e%2F5bf7867a-ed5d-48d4-a6f9-cd7a3ab14166%2Fgtfmfkk_processed.jpeg&w=3840&q=75)
