CHEN 3101 Chapter Notes - Chapter 2: Polytropic Process, Thermodynamic Cycle, Thermodynamics
Document Summary
2. 1. 2 potential energy: model 2. 7, model 2. 8, model 2. 9, the quantity mgz is the gravitational potential energy, model 2. 10. 2. 1. 4 conservation of energy in mechanics: model 2. 11. A particular interaction can be categorized as a work interaction if it satisfies this criterion. 2. 2. 1 sign convention and notation: sign convention, w>0: work done by the system, w<0: work done on the system, work is not a property of the system or the surroundings. 2. 2. 2 power: the rate of energy transfer by work is called power, and is denoted by w, model 2. 13, model 2. 14, in si, the unit for power is j/s, called the watt. 2. 3 modeling expansion or compression work: model 2. 15, model 2. 16, model 2. 17. 2. 2. 4 expansion or compression work in quasiequilibrium processes: quasiequilibrium process, is a process in which the departure from thermodynamic equilibrium is at most infinitesimal.
