A multifluid manometer is a device used for measuring the pressure of a fluid (typically a gas or liquid) by using more than one fluid to help create a readable scale. These devices often involve the use of liquids of different densities, which makes them useful in measuring a wide range of pressures, including very

A manometer is commonly used to measure small and moderate pressure differences. A manometer consists of a glass or plastic U-tube containing one or more fluids such as mercury, water, alcohol, or oil. To find the Absolute pressure: For further Queries :

When pressure is exerted by a fluid, such as in a liquid column e.g., water or mercury in a barometer), the pressure at a depth is given by the formula: Density acceleration due to gravity height For further queries :

A barometer is an instrument used to measure atmospheric pressure, which is the force exerted by the weight of the air above us. The pressure is usually expressed in units like millimeters of mercury (mmHg), pascals (Pa), or inches of mercury (inHg). There are two main types of barometers: mercury barometers and aneroid barometers. The

The absolute pressure of a vacuum chamber refers to the total pressure inside the chamber, including both the pressure exerted by the air (or gas) inside the chamber and the atmospheric pressure outside it. Absolute pressure is measured relative to a perfect vacuum, meaning it includes the atmospheric pressure as part of the reading. In

Capillary rise refers to the phenomenon in which a liquid rises or falls in a narrow tube due to surface tension.  This occurs because of the adhesive forces between the liquid and the surface of the tube, as well as the cohesive forces between the liquid molecules themselves. When the liquid’s adhesive forces to the

Viscosity is a measure of a fluid’s resistance to flow or deformation. It quantifies the internal friction within the fluid as its molecules move past one another. A higher viscosity indicates a thicker fluid that resists flow more, while a lower viscosity indicates a thinner fluid that flows more easily. Where: L = Length of

An important parameter in the study of compressible flow is the speed of sound (or the sonic speed), defined as the speed at which an infinitesimally small pressure wave travels through a medium. Speed of sound is given by the formula : Where: c –  Speed of sound in m/s k – specific heat ratio(1.4)

Density: Density is a measure of the mass per unit volume of a substance. It indicates how much matter is packed into a given space. P – Pressure in kPa R – Gas constant of air ( 0.287 kPa·m^3/kg·K) T – Temperature in Kelvin(K) Specific Gravity: Specific gravity is the ratio of the density of
