1 unit 61: ENGINEERING THERMODYNAMICS unit code: D/601/1410 QCF level: 5 Credit value: 15 OUTCOME 1 TUTORIAL No. 2 THERMODYNAMIC SYSTEMS 1. Understand the parameters and characteristics of thermodynamic systems Polytropic processes: general equation pvn=c, relationships between index `n' and heat transfer during a process; constant pressure and reversible isothermal and adiabatic processes; expressions for work flow Thermodynamic systems and their properties: closed systems; open systems; application of first law to derive system energy equations; properties; intensive; extensive; two-property rule Relationships: R = cp cv. and = cp/cv When you have completed this tutorial you should be able to do the following. Explain and use the First Law of THERMODYNAMICS .

Heat transfer. Heat transfer rate. Work transfer Work transfer rate (Power) 1.1. HEAT TRANSFER Heat transfer occurs because one place is hotter than another. Under normal circumstances, heat will only flow from a hot body to a cold body by virtue of the temperature difference. There are 3 mechanisms for this, Conduction, convection
