| DESCRIPTION | - Fundamental concepts Equation of state, Internal energy, Enthalpy. Zeroth Law, and First Law of Thermodynamics. - Non-Flow Processes for gases and Vapour Properties of Liquids and Vapour (Steam), Use of Tables and Charts for steam. Steady Flow and Non-Flow Energy Equation. Application of the Energy Equation to Non-Flow and Flow problems, Filling of a rigid vessel from a main (non-steady). - Second Law of Thermodynamics, Carnot Cycle, Absolute thermodynamic Temperature Scale, Entropy and Reversibility, General thermodynamic relations. Exergy. Corollaries of the second Law. - Properties of Mixtures: Perfect gas mixtures; P, V, T relationship, Parts of mass; Parts of volume; Internal energy; Enthalpy; Specific heats and entropy of mixtures; Gas and vapour mixtures; Psychrometric chart. Study-unit Aims: To familiarise students with properties and thermodynamic calculations for flow and no-flow systems. Introduce steam properties; Introduce students to the laws of thermodynamics. Energy conservation, and second law. Discuss differences between heat and work even though they have same units; To familiarize students with mixtures of gases and also mixtures of gases with vapour, for example water vapour in air ( moisture/humidity) analysis of thermodynamics cycles, gas and vapour. Humidity is very important in air-conditioning applications. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: Provide a written calculative analysis of thermodynamic flow and non flow processes; Be able to provide a written calculative analysis of steam processes; Determine moisture related properties from the Psychrometric chart. 2. Skills: By the end of the study-unit the student will be able to: Categorise between flow and non flow processes; Apply the appropriate analysis for the flow or non flow process; Be able to analyze a steam process; Be able to generate calculations for heat and work involved in processes that flow/non-flow and gas/vapour. Main Text/s and any supplementary readings: - Eastop and McConkey, Applied Thermodynamics for Engineering Technologists. - Rogers & Mayhew, Engineering Thermodynamics Work and Heat Transfer. |
