PROPERTY DIAGRAMS AND STEAM TABLES ThermodynamicsSummaryThe important information from this chapter is summarized below.Property Diagrams and Steam Tables Summary• The Mollier diagram can be used to determine various properties of a fluid.Mollier diagram is an h versus s plot.Can only be used when quality is greater than 50% and for superheatedsteam.Contains a series of constant temperature, constant pressure, constantmoisture content, and constant superheat lines.• The steam tables can be used to determine various properties of water using thefollowing equations.v = xv_{g}+ (1 - x)v_{f}h = xh_{g} + (1 - x)h_{f}s = xs_{g} + (1 - x)s_{f}x =vv_{f}v_{fg}x =hh_{f}h_{fg}x =ss_{f}s_{fg}• The change in enthalpy of a fluid as it passes through a component can bedetermined using a Mollier diagram on steam tables.HT-01 Page 52 Rev. 0
