MANOMETER :- U-TUBE DIFFERENTIAL MANOMETER

(FLUID MECHANICS OR HYDRAULICS)

 

DIFFERENTIAL MANOMETER

A device which is used to measure difference of pressure between the two fluids which are flowing through the two different pipes or in same pipe at two different points is known as DIFFERENTIAL MANOMETER.

 

TYPES OF DIFFERENTIAL MANOMETERS

There are two types of differential manometer as given below:-

1] U-Tube Differential Manometer

2] Inverted U-Tube Differential Manometer.

 

U-TUBE  DIFFERENTIAL MANOMETER

There are two types of U-Tube Differential Manometer :-

A] U-Tube Differential Manometer at the same level.

B] U-Tube Differential Manometer at the different level.

 

A] U-Tube Differential Manometer at the same level:

In this type of Manometer, two pipes are in parallel condition. This type of Manometers are used for measuring the fluid pressure difference between these two pipes.

For Derivation please watch the video whose link is as given below.

B] U-Tube Differential Manometer at the different level:

In this case this type of manometer are used where two pipes are at different place, not in parallel condition. This type of manometers are used for measuring the fluid pressure between these two pipes.

For Derivation please watch the video whose link is as given below.

 

2] INVERTED  U-TUBE DIFFERENTIAL MANOMETER

The inverted U-Tube Differential manometer is reciprocal of U-Tube Differential manometer at the different level. This type of manometers are used to measure accuracy of small difference if pressure is increased.
