Objectives:

At the end of this series of lectures students should:

• have a sound understanding of the First and Second Laws of Thermodynamics and some of their more direct consequences;

• be able to employ thermodynamic functions and charts to analyse the performance of engineering cycles and flow processes;

• be able to describe the behaviour of real substances over a wide range of temperature and pressure;

• be able to determine the effects of temperature, pressure and composition on vapour-liquid, liquid-liquid and solid-liquid equilibria;

• be able to apply thermodynamic principles to investigate equilibria in gas mixtures, solutions and between gases and solids.

Content:

Review of the First Law and the Second Law of Thermodynamics, definition of terms associated with these laws, some direct consequences of the First Law and the Second Law. Primary thermodynamic functions (P, V, T, U and S) and the Maxwell relations, auxiliary functions (H, G and A) and conditions of equilibrium. Application of thermodynamics to flow processes. P-V-T diagrams of pure substances, ideal gas and departure from ideality, equations of state, fugacity. Calculations of thermodynamic properties and thermodynamic charts. Isentropic expansion in nozzles and nozzle efficiency, vapour and gas power cycles, compressors and expanders, turbines, refrigeration and gas liquefaction. Availability and use of availability in the analysis of processes. Partial molar quantities, chemical potential and activity coefficient, gas mixtures and liquid mixtures, dilute solution, solubility of a gas in a liquid and a solid in a liquid. The phases rule, phase equilibria in one component systems, two-component systems (vapour-liquid, liquid-liquid and solid-liquid systems) and three-component systems.
