Answer 2

An open tube manometer has two arms.

Explanation: Open tube manometers:

• Open tube manometers are known as U-tube manometers.
• U-tube manometers are U-shaped tubes that are partially filled with a fluid, generally water or mercury.
• There are two arms in the U-tube manometers, each arm is filled with the fluid of the manometer.
• One arm is attached to the vessel that is filled with the fluid whose pressure is supposed to be measured.
• Another arm remains open so the fluid present in the tube can rise or fall.
