| Abstract | A cubic equation of state and combining rules for mixtures containing steam has been developed The equation is based on the earlier equations of Clausius, Martin and Kubic, and contains two temperature-dependent parameters, which give it enough flexibility to fit the residual properties of both steam and non-polar fluids with sufficient accuracy. Mixture properties are calculated using pseudo-critical parameters for steam and a single temperature-independent interaction parameter ξ in the combining rule Tc12=ξ(Tc1Tc2)½. For mixtures such as steam–carbon dioxide, where there is a specific interaction between the unlike components, ξ must be obtained from cross-term second virial coefficients. Where there is no specific interaction ξ is given by ξ= 2(Vc1Vc2)½Vc12–1(I1I2)½(I1+I2)–1. The equation of state fits measurements of the excess molar enthalpy HEm of mixtures containing steam at pressures of 0.1–10 Mpa, at temperatures up to at least 700 K, and allows the calculation of (p, Vm, T) properties. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
