ENGR 360 Lecture Notes - Lecture 2: Thermal Equilibrium, Control Volume, Phase Rule
Document Summary
31-08-2018 - ch 1 - states - lecture 2. State of equilibrium: can be described a set of properties. The state postulate: the state of a simple compressible system is completely specified by two independent, intensive properties. A process during which the initial and final states are identical. Quasi-static or quasi-equilibrium: proceeds in a manner such that the system remains infinitesimally close to an equilibrium state at all times. Steady flow process: process during which fluid flows through a control volume steadily. Fluid properties within a control volume may change with position but not with time. If two bodies are in thermal equilibrium with a third body, they are in thermal. If two bodies are in thermal equilibrium with a third body, they are in thermal equilibrium with each other. Pressure: a normal force exerted by a fluid per unit area.
