A(n) ____ can be connected to measure the velocity pressure of the air moving in a duct.

Barometer
Pitot tube
Hygrometer
Manometer

The correct answer is: Manometer

A manometer is used to measure the velocity pressure of the air moving in a duct. It works by comparing the pressure in the duct to a reference pressure to calculate the velocity pressure accurately. A barometer measures atmospheric pressure, a hygrometer measures humidity levels, and a pitot tube is used to measure fluid flow velocity.
