Question

​​​​​​​

Examine the below diagram of a manometer which is filled with water and air. It is a differential U-tube manometer being used to measure the difference in pressure between two taps labelled ( A )

Answer 1

A manometer is a device used to measure pressure. It consists of a U-shaped tube partially filled with a liquid, typically mercury. In a closed-end manometer, the pressure of the gas can be determined by measuring the difference in height of the liquid in the two arms of the U-tube.

Step-by-step explanation:

A manometer is a device used to measure pressure. It consists of a U-shaped tube partially filled with a liquid, typically mercury.

One end of the U-tube is connected to a gas chamber, and the other end is either closed or open to the atmosphere. In a closed-end manometer, the pressure of the gas can be determined by measuring the difference in height of the liquid in the two arms of the U-tube.

If one arm is open to the atmosphere, the manometer can be used to measure gauge pressure.
