coronavirus and other germs and viruses...Reimers also has easy to use portable sterilizers too!
Testing done at DHS' advanced bio containment lab in Maryland, said the virus' half life plunges "drastically" with exposure to higher temperatures and even minimal exposure to humidity.
Feb 26, 2012· I am currently working on designing of a fire tube boiler. I have to calculate the heating surface area. I ve heard a rule of thumb that 1 sq ft of area is required to produce 7 lbs of steam. I firstname.lastname@example.org > Get A Quote >
File Size: 139KB One of the common misconceptions engineers have about boiler performance is that the more surface area, the better. This is far from truth in most cases. The basic equation for heat transfer across a surface is: Q = USDT where Q = energy transferred U = overall heat-transfer coefficient S = surface area DT = log mean temperature email@example.com > Get A Quote >
