Question

In a manometer, the two ends of a tube are connected to points where

• A. pressure difference is to be measured
• B. velocity difference is to be measured
• C. density is to be measured
• D. power difference is to be measured

Answer 1

Answer:

A. pressure difference is to be measured

A manometer is used to measure pressure difference between two points. It consists of a glass tube connected to a point where pressure is to be measured and an open end to the atmosphere. Differential manometers measure pressure difference between two points in a fluid system using a U-tube containing a heavy liquid.
