Steam Turbine Rotor Needs to be Rebladed

The new blades are going to be manufactured using reengineering approach. In this case the grooves measurement is important, to do it the grooves should be cleaned to get rid of a scale ( I am not sure if "scale" is a proper word). A method we using to get the grooves cleaned is aluminiun oxide blas

J. F Kennedy "Bullet"

Hi

Still the mystery surrounding assassination of J.F.Kennedy 1963, its surprising with developments on science that nobody has come up with solution as to how many/who was involved (weapon's fired). With all the still photo's and newsreels available, bullet(s) would be in pictures! And sho

P-91 Welding

ASTM A335-09a, paragraph 9.3 specifies a hardness range for the finished materail (Post heat treatment), however, both ASME B31.1 and ASME Section I do not specify a maximum hardness for PWHT of the welds. Is there an industry standard (Refinery, Power, etc) that establishes a "best practice" hardne

Getting Rid of House Odors

Product Review: SteelSeries Siberia Headphones

If you're like me and listen to lots of music, headphones are a necessity. I have a pair that I keep at home, a pair for working at the office, and a pair for when I'm outdoors. Recently, the Sennheiser PC156 headphones that I'd been using in the office started showing some wear and tear. They

203ºF vs 212ºF For Brewing Coffee

I'm watching a bit on TV about brewing coffee. They say that 203°F is the ideal brewing temperature.

They say that if the water boils it "burns" the coffee. So, if we assume that, at sea level, water boils at 212ºF is this enough added heat to spoil the coffee?

Or, is it the re
