Question

differential U tube manometer ka equation Kya Hota Hai

Answer 1

Hi,

Here is your answer,

                                  U/OPEN TUBE MANOMETER 

Open tube manometer/ U- tube manometer is used to measure pressure difference.It consists of U-tube shape tube containing a liquid having low density such as oil to measure the small pressure difference and mercury as the high density to measure the large pressure differences.One end of the tube is open to the atmosphere and the other end is joined with a flask, whose pressure we want to know.

 EQUATION

The pressure p at point A is equal to pressure at point B.

 ∴    →     pa = pb (Pascal's Law)

      →    pb = pa + hρg

      →    pb = pa + ρgh


Hope it helps you !
