2.31" to prove this all one does is to take 2.31 x .434 and there is your proof
set the pressure relief valve
If you evacuate all the air between 2 pieces of glass, the glass is pressed together by atmospheric pressure from the outside. By measuring the force needed to separate the panes of glass, one can extrapolate the pressure exerted on the glass.
Yes, you can join water high pressure hoses by using a hose connector or adapter specifically designed for high pressure applications. Make sure the connections are secure and leak-proof to prevent any issues during use.
Not a maker's mark, but a government PROOF mark. Several European nations require that firearms go to a government test facility, where they are examined, and fired with a high pressure test cartridge to prove their safety. Used since 1904, your proof mark is from the Birmingham England proof house.
A proof coin of any type and date is one that's specially struck for sale to collectors. The blanks used for proof coins are highly polished and they're struck at slower speeds by high-pressure presses to produce a sharp, better-detailed image. As of 04/2012, an 1896 proof Liberty nickel retails for anywhere from $150 to over $2500 depending on the quality of the strike.
An indirect proof is a proof by contradiction.
i just have to relaxe myself and taking piecefull mind in every situation and take these conditions as a challenge to grow ownself and proof ownself
Proof coins are ones which have been minted more slowly and under greater pressure than normal circulation coins. This ensures all the detail in the dies is fully struck up. Normally the dies and blanks are polished, but sometimes the dies are sandblasted to give a matte appearance. A good example is the 1902 proof set of Great Britain.
