Proper ventilation of laboratory settings is required to promote and maintain laboratory safety and protection to life and property. Items such as fume containment, worker safety, proper cleanliness through pressure relationships, filtration, air changes per hour ACH , point of fume capture, temperature, and relative humidity requirements are elements necessary to design the ventilation system depending on the laboratory type. Codes identify ventilation measures to provide minimum requirements for the protection of life and property through prevention and control of fumes and containment of hazardous fumes and contaminants for worker safety.

chemical engineering: Rule-of-thumb For Minimum Flow Recycle

When you need to clean up a spill or wipe down the kitchen table after dinner, what do you reach for first? Paper towels are an obvious choice, but there's actually a more affordable, less-wasteful alternative than your go-to bulk pack: Swedish dishcloths, also known as reusable paper towels. Patented in by Swedish civil engineer Curt Lindquist under the brand name Wettex, reusable paper towels are typically made of a cellulose-and-cotton blend, and they're meant to be dampened, squeezed out, and used to sop up spills or clean up crumbs, just as a regular paper towel would. They're slightly spongier than paper towels when wet, but they feel just like paper when dry. These quick-drying cloths come in all sorts of colors and patterns, and many brands claim that they can be used for a few months before throwing away or composting. As a general rule of thumb, don't compost anything that's been used with a chemical cleaning spray.

There was a time when this would have shocked me, but now, because of the society we live in, scenes like this are commonplace. I named him that because he's so good at what he does. You wanna try him out?

And secondly because the figures used to claim salaries are high are usually broken down by the subject studied at university not the actual job being done. Figures released this week by the Times Good University Guide fall into this category. They show that six of the top ten highest earning subjects based on starting salaries are engineering disciplines.
