Answer:

Hence the given statement is false.

Step-by-step explanation:

For low-speed subsonic wind tunnels, the air density remains nearly constant decreasing the cross-section area cause the flow to extend velocity, and reduce pressure. Similarly increasing the world cause to decrease and therefore the pressure to extend.

The speed within the test section is decided by the planning of the tunnel.

Thus by adjusting the pressure difference won't change the worth of test section velocity.
