Bug #73204 for Physics-Psychrometry: sub dbw2v

Hi MikeM, I know it was derived from another source, and you may not maintain this, but the function dbw2v uses 273.16. I think it is converting from Celcius to Kelvin so it should be 273.15. Yes, it's a very small difference. :) Cheers, Dave Physics::Psychrometry-1.0 This is perl, v5.10.0 built for darwin-thread-multi-2level (with 2 registered patches, see perl -V for more detail) Darwin pecan 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386

Hi Dave Thanks. I will look at it soon. Cheers Sent from my iPhone On 13/12/2011, at 3:59 AM, "Dave Ahijevych via RT" <bug-Physics-Psychrometry@rt.cpan.org> wrote: Show quoted text

Hi Dave, we have double-checked this figure and 273.15 is correct. See for example CRC Handbook of Chemistry and Physics, page F-76, 'Temperature'. or http://en.wikipedia.org/wiki/Absolute_zero and http://www1.bipm.org/en/si/si_brochure/chapter2/2-1/2-1-1/kelvin.html Cheers.

Hi, I probably was not clear. And I am looking at the version on http://cpansearch.perl.org/src/MIKEM/Physics-Psychrometry-1.0/lib/Physics/Psychrometry.pm As it is now, the code uses 273.16, not 273.15. It needs to be changed from 273.16 to 273.15. -Dave On 12/30/11 12:43 AM, MIKEM via RT wrote: Show quoted text

Hi Dave, sorry for my misunderstanding. You are quite right. New version 1.1 has been uploaded to CPAN. Thanks. Cheers. On Fri Dec 30 11:27:57 2011, ahijevyc@ucar.edu wrote: Show quoted text
