Unformatted text preview: system? Ideal Gas Equation of State p = RT where R is the universal gas constant pV = mRT since = V/m V is system volume, m is mass p = RT since = /M, R = R/M M is the molecular wt. pV = nRT since = V/n n is the number of moles Values for the universal gas constant R = 8.314 kJ/kmol K R = 1.986 Btu/lbmol R R = 1545 ft lbf/lbmol R Assumptions that go along with the Ideal Gas Model 1. 2. p v T Diagrams pv and vT diagrams often prove useful in solving thermo problems Features: Singlephase regions, Twophase regions, Triple line, Saturation states, Vapor dome, Critical point....
