New features of this innovative text include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications. Shankar has introduced major additions and updated key presentations in this second edition of Principles of Quantum Mechanics. You show a 'Virtual' Temperature under Thermodynamic properties.R. What is the difference between the six different humidity metrics shown? Why does this program show two different values of specific volume? There appears to be error in the calculations when converting from one unit system to User may override default input by selecting and entering new value. Site elevation for Dayton, OH - 997 ft amsl (306 m) based on the ASHRAE HOF. Sea Level Pressure - 14.7 psia / 101.3 kPa / 29.92 in Hg / 760 mm Hg (Default when 'ActualĪverage Barometric Pressure in Dayton, OH - 14.18 psia / 97.7 kPa / 28.86 in Hg / 733 mm Hg At the end of the calculation, the user has the option to convert from the English to the SI (or vice versa) unit system. The user then enters a desiredĭry Bulb temperature and one of three humiditymetrics:ĭew Point temperature.
To calculate properties, the user must enter either a site elevation (from which an average barometric pressure is calculated) or an actual barometric pressure. It will also provide a number of other thermodynamic properties not found on a typical psychrometric chart.
This on-line program calculates typical psychrometric state point properties. Instructions for the Psychrometric Calculator
