Steam Table, A complete IAPWS IF-97 standard

[Powersoft]

Hi all,

Please find my implementation of the Steam Table for the HP-Prime

It is based on the version of :
X Steam, Thermodynamic properties of water and steam.
by Magnus Holmgren

30 Jan 2006 (Updated 01 Aug 2007)
Water properties A complete IAPWS IF-97 standard.

It is still in progress! Next step is to make a nice App.
All functions are implemented, except he transport functions!

Small help:
Water and steam properties according to IAPWS IF-97.

This Steam Table provides accurate steam and water properties from 0 - 1000 bar and from 0 - 2000 deg C according to the standard IAPWS IF-97.
For accuracy of the functions in different regions see IF-97 (http://www.iapws.org)

Great Brother¡¡¡¡¡ u have a new fan now¡¡¡ excellent Job

[mop80087]

Hi,

that's a hard job, thank's for the great work

[Powersoft]

Hello,

I have add two transport properties for this steam table.
Dynamic Viscosity and Thermal Conductivity are now added.

Have fun with it.

Hello, I'am from Argentina, I have a problem when I try to run the program, a sintaxis error appears in the screen.
The error is
"syntax error in program line 4"
I hope that you can fix it or help me!
This program is so useful to me, I study engineering!

Thanks!

Do you use the latest update from HP, because with the latest version I have also some problems.

I fond the solution, some fixes in the code and all ok!
Works perfectly!
Thanks!

[Ziz]

Thanks a lot! Its a great job. But has a sintaxe error. Does anyone know how to fix?

Thanks.

[roadrunner]

Ziz,

Use the connectivity kit and find line 3294. Change it from this:

LOCAL TMax,hMax,hMin,hB,vmax,hV;

to this:

LOCAL Tmin,TMax,hMax,hMin,hB,vmax,hV;

Then it should compile with no syntax errors.

[roadrunner]

In the newer version that would be line 3305.

It worked! Thank you very much!

Hi,
Please excuse me if this is very basic but I received the calculator just yesterday
I have the code installed and I can run the functions from the "program" menu.
However, I would like to run them from home or from other programs.
I tried: (from home)
Tsat_p(1)
and it gives me syntax error
How can I do it ?
Thanks !!

Hello Frikosal,
First of all, HP Prime is a case sensitive calculator, and the correct call for this function should be tsat_p(1) instead of the Tsat_p(1), also you can access all functions of this program by the toolbox menu inside User > Steam97. The toolbox button is the one just bellow the Num button.


Secondly, make sure you managed to fix the source file as posted by roadrunner above.

[f.prisinzano]

Hi,
I tried to load the progaram but I can't because the calculator crashes during loading.
Someone has a suggestion?

Thanks

[Freire]

Can you specify exactly what happens?
Also, what calculator are you using and firmware version if possible.
I'm just a user here, but can help =]

Make sure you followed these steps as well.

[f.prisinzano]

Hi, I installed the program, I corrected the line 3305 but I still obtain the syntax error message. Furthermore, I don't visualize the functions on user menu.

How can I fix it?

Thanks

[Berg]

The program not run. Just appears an exclamation point (!)

What to do ?

[dartagnan993]

Hello everyone, i just bought the HP Prime and i would like to install this program but i don't know how. I tried to paste de file i downloaded here in the "programs" section of the calculator from the HP Connectivity kit but as i turn on the HP Prime i just dont see it. Can you please help me?

[Randall]

The connectivity kit has a content area and is labelled as such. Programs and other data in the content area reside on the computer with the connectivity kit.

Each connected calculator (such as a hardware Prime or a virtual Prime) will also be displayed. Each connected Prime has its own work area.

The content area is independent from the calculator(s) work area.

I have steam97 on my Prime. Typing shift program lists my programs as well as steam97.

Since you don't see steam97 on your Prime, it is possible steam97 was downloaded to the content area of the connectivity kit and not the calculator work area.

Hi Powersoft, congratulations on your program.
I ask you permission to translate it into Spanish to use it with my students in Spain.
Thank you very much.
