- 5. A wind tunnel consists of an entry contraction, a constant-area working section of area 0.5 m?, a diffuser and a fan of area 1 m?, as shown in Fig. 2. The air is pulled from the atmosphere through the contraction into the working section where its speed is 20 m/s, and from there it flows through the diffuser into the fan, which returns it to the atmosphere.
