To calculate the difference in pressure, multiply the difference in height by the density of the gas and the acceleration due to gravity. He also holds a Bachelor of Arts degree from that university, receiving honors for his B.A. Differential manometer; Inverted differential manometer; McLeod gauge. When a weather forecaster speaks of a barometric pressure of so many millimeters (mm) of mercury, it can mean that the pressure difference between the inside and the outside of a storm will push the mercury up a differential manometer tube by that amount. However, unless otherwise qualified, the term manometer most often refers specifically to a U-shaped tube partly filled with fluid. The simplest device for measuring pressure and differential pressure (DP) is the manometer or differential manometer. It is able to measure either positive, negative, or differential … 3.2.1 Types of Manometers. By measuring the difference between the heights of liquid, it is possible to calculate the difference in pressure. … Pressure is a measure of the amount of force (F) that is exerted per unit area (A): The unit of measure for pressure is, therefore, a force value divided by a squared distance value. You can easily build this type of manometer as part of a laboratory experiment to demonstrate the effect of air pressure on a liquid column. The change in pressure from one place to another can be determined by the difference in height of the fluid in the two arms.
