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 superheated
steam.
Contains a series of constant temperature, constant pressure, constant
moisture content, and constant superheat lines.
•
The steam tables can be used to determine various properties of water using the
following equations.
v = xvg + (1 - x)vf
h = xhg + (1 - x)hf
s = xsg + (1 - x)sf
x =
v
vf
vfg
x =
h
hf
hfg
x =
s
sf
sfg
•
The change in enthalpy of a fluid as it passes through a component can be
determined using a Mollier diagram on steam tables.
