Choi · Answer 1

b) false

Explanation:

As we know that

Volume flow rate Q

Q = A x V

For constant volume flow rate, if velocity will increase then automatically area will decrease and vice versa.

Generally nozzle are used to increase the velocity and diffuser are used to decrease the exit velocity of flow.

So by increasing the cross sectional area of the restriction, the velocity of the flow will decrease.
