The Differential Manometer
The Differential Manometer Equation
Cancel and then group terms to get:
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.
