Use the density of mercury to obtain the mass, and … WebThe applied pressure can be measured as absolute, gauge or differential pressure. Pressure can be measured directly by measurement of the applied force or indirectly, e.g. by the measurement of the gas properties. Examples of indirect measurement techniques that are using gas properties are thermal conductivity or ionization of gas molecules.

5.2: Gas Pressure and Its Measurement - Chemistry LibreTexts

Pressure measurement is the measurement of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure mechanically are called pressure gauges, vacuum gauges or compound gauges (vacuum & pressure). The widely used Bourdon gauge is a mechanical device, which both mea… WebHead Pressure. Head pressure is the pressure exerted by a liquid that indicated by height of the liquid in a liquid column. It depends on; 1. the height of the liquid column. 2. the relative density of the liquid. Pressure head = R.D x h x 9.8 kPa. where, R.D = relative density of the liquid, h = the height of the liquid g = gravitational force. how many gs do you experience in a rocket
