Change in height in manometer Calculator

In a manometer, the change in height (Δh) refers to the difference in the liquid column’s height between two points in the U-tube. It is a crucial parameter used to measure pressure differences in a fluid system. The manometer typically consists of a U-shaped tube partially filled with a liquid (e.g., mercury or water) and open at both ends. One end of the U-tube is connected to the point where the pressure is being measured, and the other end is usually open to the atmosphere or connected to a reference pressure. The change in height (Δh) is determined by the pressure difference (ΔP) between the two points in the fluid system.

  • Pa: Atmospheric pressure 
  • ρ: Density of the fluid in the manometer 
  • g: Acceleration due to gravity 
  • Δh: Change in height
