The programm will be freeware. My gasmixer will have vdWaals algoritm and all kind of extra's in it; = f.e. it can be used =20 a. to mix the 300bar with 10 % overfill (5000 psi ) ; b. check the mix with a 85 euro balance ( theoretically helium accurate = within 1% ) ; c. displaying sensor signals like O2, pressure, ..... ; d. just name it .... 256 Mb is a lot of programming code. Anyhow ... a lot is allready programmed ... in dutch with metric units. = Also now i'm converting it into English with switch for metric/imperial units.=20 But at the moment i have a problem with the cuft cylinder capacity. In = the Metric system we define cylinders with water capacity and max. fill pressure. f.e. we have = 12l/200bar, 12l/232bar and 12l/300bar. It's very easy to integrate this water capacity into the vdWaals = algorithm's. To use imperial units, the cuft capacity has to be converted into water/ 14.5 psi capacity. =20 http://www.mdaguam.com/tankspecs.htm and the conclusion that the = convertion cannot be done with=20 a algorithm. f.e.( according this ) the cuft of the low pressure = cylinders =3D water capacity * fill pressure + 10 % ??????????????????????? hellllllllllllllllllllppppppppppp. = When i see the high presssure cylinders 80 cuft =3D 77.4 cuft , and here it looks like that + 15% is = choosen ???????????? more help. Are these data correct ? isn't there any defintion of the cuft ? So = when this correct, the only way to let my programm function with imperial units, is to bring in a lot of = database with all kind of cylinders and an interface to choose one of them. ( that's for fun ???) please give me some information/advice =20 Frank ------=_NextPart_000_0005_01C2F584.17A458D0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2800.1106" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>hello list,</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT> </DIV> <DIV><FONT face=3DArial size=3D2>just for fun programming, i'm writing a = palm pda=20 application for gasmixing.
