In  my line of work, torr equals atmospheric pressure.
any pressure above torr is positive pressure.
any presure below torr is negative pressure.
I use it alot with patients being mechanically ventilated.

I know that was absolutely no help, yet I felt compelled to reply :?  :roll:

Another important unit of measurement is millimeters of mercury, abbreviated mm Hg (Hg is the chemical symbol for mercury). Some texts refer to mm Hg by the term "torr," after the Italian Evangelista Torricelli (1608-1647), a pioneer in the measurement of atmospheric pressure; one mm Hg = one torr. Air pressure at sea level is 760 mm Hg (or 760 torr). In medicine and science, mm Hg is commonly used as the unit for partial pressures of gases.

Dear doctor Bob.. I had Ham and bean soup for lunch today and now I have a problem with excessive gaseous production.. What if any would be a good unit of approximate measurement to use while talking with my doctor..   :?:  :?:  :?:  Torr sounds good and I dont know if you know but mercury is illegal to use in the usa for testing now days.. Also I dont know s^&t about the metric system so how many mickey mouses per
rectal out burst would be too much  :?:
I read your column every day and although abby is my favorite your 2nd in line ..

Bugpac are you going to try to vacuum mold your parts? I saw that done on a show called dream car garage ,the results are supposedly worth the extra effort.

yes i am going to try, i cant vacuum the main body, but i can do all the components, I also am looking at infusion molding, were i lay it up dry, pull vacuum and the let the resin in via supply line, vacuum pulls the resin thru the dry glass, but thats down the road...
