Lesson: The Liquid Column Manometer Physics • Second Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe the process of pressure measurement using the height of a liquid column in a U-shaped tube.

Students will be able to

recognize that the ratio of the column heights in a U-shaped tube is equal to the ratio of the pressures on the tops of the two columns,
recognize that the difference between the column heights in a U-shaped tube is equal to differences of the pressures on the tops of the two columns.
