[Lancaster] Software development

[Ken Hough]

Martyn,

wrt our discussion about software development:

re my steam/water properties app.:
This presently includes functions which (fairly accurately) define 
various properties of steam and water (eg Hg, Hf, Sg, Sf, Vg, Vf) over 
the entire practical ranges of temperature and pressure including the 
superheat region up to 250 bar and 650 degC. Might sound boring, but 
engineers dealing with the topic might find these useful. The app. is 
written in (ANSI) 'C' and uses the ncurses library.

The app. uses the property functions either on a simple 'lookup' basis 
(cp the old steam tables) or to carry out calculations including amount 
of steam required for heating and power generation via steam turbines -- 
lot's of itterative calculations here. It can save a lot of paper work!

The property functions are fairly well checked. There are just a couple 
of bugs in one of the turbine options, which I could sort out given some 
motivation.

If any of your contacts are interested, let me know.
