The Differential Manometer Equation

Cancel and then group terms to get:

Differential manometer attached to a pipe with a fluid flowing through it

Cancle equal terms
Cancle equal terms

A differential manometer measures the pressure difference between two points, in this case P1 - P5.

Given h, ρm and ρw, determine P1 - P5.

What do we know ?

Apply the Barometer Equation to determine P2 relative to P1 and P3 relative to P5.
