Standard barometric pressure hg
WebbIt is convenient to have a standard reference atmospheric pressure, which is 760 mm HG or even 29.92 in Hg at 32F, or 14.696 psia (14.7 typical), or 1 atm. Pressure is one of the most useful thermodynamic properties because it is easily measured directly. Pressure-measuring instruments read a difference of pressures, called gage pressure; Webb23 ft^3 of air was drawn from a ventilation duct and measured by means of a dry gas meter. the meter's temperature averaged 60 F and the meter gage pressure was -1.9" H2O. Barometric pressure during the sampling was 752 mm Hg. Calculate the volume in standard cubic feet and in standard cubic meter (25C, atm) this is an ideal gas problem

WebbThe mercury would rise or fall depending on the pressure difference, so you would literally be measuring millimeters of mercury (mmHg). In the past, mmHg was just one torr, but due to more rigorous definitions and redefinitions, the standard mmHg is … Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards. Other organizations have established a variety of alternative defi…
