Unit 4 dealt with ideal and real gasses under which various topics such as properties of ideal gas, equations of state for ideal and real gases-reduced properties, compressibility factor and generalized compressibility chart are discussed.Unit 3 deals with properties of pure substances, phase rule, p-V, p-T, T-V, T-s, h-s diagrams, PVT surfaces, determination of dryness fraction, application of I and II law for pure substances, ideal and actual Rankine cycles, cycle improvement methods such as reheat and regenerative cycles, economiser, preheater, binary and combined cycles.
Unit 1 deals with basic concepts of thermodynamics such as concept of continuum, microscopic and macroscopic approaches, path and point functions, intensive and extensive properties, total and specific quantities, system and their types, thermodynamic equilibrium state, path and process, quasi-static, reversible and irreversible processes, heat and work transfer, displacement work and other modes of work, P-V diagram, Zeroth law of thermodynamics, concept of temperature and thermal equilibrium, relationship between temperature scales, and new temperature scales.
