How to use a Manometer to find Pressure Difference?
When it comes down to taking the FE Exam, you can count on needing to know how to use a Manometer to find Pressure Differences.
These problem types, found within the Fluid Mechanics portion of the exam, tend to work around one of three manometer types:
- Single Column Manometer
- U-tube manometer
In this video, we dive into part 1 of an FE Exam Practice Problem on the subject of FLUID MECHANICS OF LIQUIDS, showing you how to quickly and efficiently find the pressure difference using a manometer.
What is a MANOMETER?
A MANOMETER is a scientific instrument used to measure PRESSURES.
The most common MANOMETER consists of a U-shaped glass tube filled with some high-density liquid (typically mercury). This type of MANOMETER is represented in your NCEES REFERENCE HANDBOOK.
Generally speaking, when in use, the U-TUBE MANOMETER is installed in an upright position.
When exposed to the same pressure on both ends, the levels of the fluid in the two vertical columns will be equal, this is referred to as the ZERO POINT of the MANOMETER.
The MANOMETER is placed against a measuring scale to allow any difference in the height of the two columns to be noted. This height differential can be used directly to make relative comparisons between different test PRESSURES.
So how can we use a manometer to find Pressure Difference?
Check out the video and see how we can go about solving this type of problem in the most efficient manner.
