Calculates the basic thermodynamic properties of water (subcooled, superheated or saturated)

File Information
Description

This package consists of functions that calculate basic thermodynamic properties for water. All functions follow the IAPWS-97 formulation. Please note that Regions 3 and 5 have NOT been implemented. This has been programmed for use by engineering students and regions 1, 2 and 4 cover the useful range. See www.iapws.org for the paper describing the formulation in details

 The useful functions are:

 WTP_PT - return thermodynamic state and properties from given P and T
 WTP_vT - return thermodynamic state and properties from given v and T
 WTP_vP - return thermodynamic state and properties from given v and P
 WTP_uT - return thermodynamic state and properties from given u and T
 WTP_uP - return thermodynamic state and properties from given u and P
 WTP_xP - return thermodynamic state and properties from given x and P
 WTP_xT - return thermodynamic state and properties from given x and T

where P:pressure T:temperature x:quality v:specific volume u:internal
energy h:enthalpy s:entropy

MATLAB release MATLAB 6.5.1 (R13SP1)
Other requirements Should work on all platforms and Matlan versions.

If you need a vectorized version of IAPWS IF97 water/steam tables for all regions (except region 5) and thermodynamic derivatives, then please see:

Thank you.

You must erase a "end" in WTP_vT.m

a WTP_vT.m se le debe borrar un "end"

I think that you are a good programmer and you should try to improve your code efficiency in a supercritical region.
