On the Equation of State of Mercury Vapour

Abstract

In this report, new characteristic equations and tables of mercury vapour are shown, based on the results of our experiment on the relation between temperature and pressure of saturated mercury vapour, and using the experimental values of enthalpy of saturated liquid mercury by T.B. Douglas and others. The equation of state of mercury vapour obtained here is as follows : υ=RT/P-1.793×10-2(100/T)+2.51×10-2(100/T)2+1.071×10-3 where, P is pressure kg/m2, T=273.15+t is absolute temperature °K, t is temperature °C, υ is specific volume m3/kg and R is gas constant of mercury vapour 4.226 2 kgm/kg°K.
