dont forget the formula I= R/U\nsort them and u will get the answer\n\n Current: 625mA (milli amperes)\nResistance: 19.2 ohms

Silica fume has a average size distribution from 0,3 to 0,05 microns (or less) with a specific surface area from 15 to 200 m2/g.\n\nFor more information see the web site of degussa.

Sounds like a heat transfer question.  If so it depends on how the tube is being used.  \n\nFor a single pipe exposed to heat transfer to air, the outer diameter is used to determine the surface area.  For shell and tube exchangers they have charts for making the determination based on the tube configuration and baffling.

Is 4ft the radius or the diameter? (diameter is twice the radius).  Use the formula 2 x 22/7 x r  OR 22/7 x d (both of which are the same since 2r=d)

It's twice the size of A4. Wikipedia on 'ISO 216' has a nice graph showing the different sizes. For A3 it's 297 × 420mm.\nhttp://en.wikipedia.org/wiki/ISO_216

You are looking at plumbing products specifications.\nBasically the 1010 spec really covers only the thread sizes and the socket sizes for connections and copper tube.\nYou can go to KEMBLA Copper tubes website and they have full BS sizes for Copper tubes.. Any website showing BSP and BSPT threads will give you what you need there.\nWithin BS1010, each item (product ) has it's own standard dimensions.\nBasically you can measure socket sizes and use thread guages to ensure things are up to standard.\nThe trouble with British Standards is they are optional.. You don't need to comply with the standards but can still use product on the market.\nYou should also check out the european Pressure Vessel Directive which came out in 2001 I think.. They also have standards requirements for the UK market too... but really confusing.

If you desire the external surface area of the pipe,\n\nA = pi*d*L\n\nMake sure d & L are in the same units and your answer will be in those units squared.\n\nIf you are looking for the internal cross sectional area:\n\nAc = (pi*d^2)/4

4 inches. the radius is half of the diameter.

Here you have a free downloable PDF presentation from the 28 Sep 05 Conference Micro & Nano Technology (MNT) Measurement Club. I think it's worth to have a look.\n\n"Measuring Nanoparticle Surface Area and Porosity by Gas Sorption"\nMike Tucker, Quantachrome UK\nThe technique of gas sorption has long been used for the determination of surface area and pore size distribution of particulate systems and porous solids. While traditional sorption systems have proved adequate for the majority of tasks, the latest generation of ultra-fine materials, often coupled with microporosity offer new challenges to the sorption scientist. To meet these challenges many new developments have been made in the fields of analytical instrumentation and software modelling. The presentation will review some of the new techniques available, and provide examples to illustrate their applicability to the field of nanotechnology.\nDownload presentation: http://www.npl.co.uk/php/docs/download.php?area=metrology_clubs&path_name=/metrology_clubs/mnt/meetings/28sep05/presentations/connagh.pdf

1-1/14" standard weight (sch 40) steel pipe has an outside diameter of 1.660 inches and a wall thickness or .140 inches. If it is wrought iron pipe then the wall thickness is .143" \n\nFrom this you should be able to figure the inside diameter and therefore the volume per linear foot. There are 7.48052 US gallon per cubic foot
