Question

In how many categories is the supersonic wind tunnel classified into?

(a) 2

(b) 3

(c) 4

(d) 6

This question was addressed to me in unit test.

The above asked question is from Supersonic Wind Tunnels topic in chapter Compressible Flow through Nozzles, Diffusers and Wind Tunnels of Aerodynamics

Answer 1

Correct answer is (a) 2

The explanation is: Supersonic wind tunnel is broadly classified into two categories – Intermittent wind tunnel and continuous wind tunnel. Out of these two, the intermittent wind tunnel is more commonly used due to simpler design, faster start and more power available to start the wind tunnel.
