Document Summary
Entholpy is the sum of internal energy and the pressure times the specific volume n = u + p + c entholpy int. energy pressure specific volume c = 1/ density. Trouble with units, j vs kj vs mj. Thermodynamics is the studyof energy exchange and transformation. 3 components: a compressor, a combustion chamber, a turbine fuel--- comb chamber--- c --------------------------- |-------------wout air exhaust. The net work out on the pressure and temperature of point 1, 2,3and4. Energy can not be created or destory it can only change form. We are interested in: the quantity of energy, the quality of energy: how easy is it to convert the energy to a different form. Electrical energy is a higher quality than heat energy. A system is simply the region of space that we want to analyze. |------------------------------he--------------------------: the compresor is a system, the entire cycle is a system.
