Your unit for temperature is incorrect, by the way. the unit is kelvin, not degree-kelvin, if that was your intent. TTFN (ta ta for now) I can do absolutely anything. I'm an expert! https://www.youtube.com/watch?v=BKorP55Aqvgfaq731-376 forum1529 Entire Forum list http://www.eng-tips.com/forumlist.cfm Upvote 0 Downvote
