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

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"

Wonderful this is what I need

i need it,thanks for give it

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

Good programs
