You have to have access to the end opening. Use a veneer caliper or micrometer to measure the thickness. Make sure the measuring instrument is measuring a single point, not the curvature of the pipe.\n\nYou can't use a finish thickness gage, such as one used for paint.

Gauge refers to the thickness of the steel. The lower the gauge the thicker the steel. The link below is for a steel gauge chart for cold and hot rolled steel sheets. It relates gauge thickness to inches.\n\nhttp://www.coasteltools.com/tech_steel_gauge_chart.htm

Use the micrometer caliper to measure the diameter of the copper wire. \nThe micrometer caliper is used to measure distances with more precision than a vernier caliper. It has a 0.5 mm pitch screw, this means that you read millimeters and half millimeters along the barrel. Every revolution of the ratchet knob will open the jaws a half millimeter. The sleeve is divided into 50 divisions corresponding to one hundredth of a millimeter (0.01 mm) each. To take a measurement place the object between the anvil and the spindle, grip the ratchet and turn until the object is lightly gripped, do not overtighten. The first part of the measurement is taken from the barrel, each division is 0.5 mm, note that the millimeters and half-millimeters are on opposite sides of the line. Next obtain the reading of the sleeve and add this value to the reading you obtained from the barrel. \n1. Obtain the reading when the surfaces of the anvil and the spindle are in contact. This is the zero reading of the micrometer caliper, it can be either positive or negative. Record the zero reading to 0.0001 cm.

***Important Note***\nYou should consult a petroleum engineer who is familiar with the specifics of your work if you require this information for actual field work.  The sources below are fine if you are looking for general information not to be used in the field.\n\nYou need to be more specific about the information you need.  There are several 2 7/8" drill pipes available and the weight varies.  If you need to know the weight of drill pipe that has become stuck while drilling, you have to take buoyancy into account.  Try the first link for the weight and the second link for the discussion about buoyancy.

Whenever you make \na measurement, you have some error. How much the error is depends on \nthe equipment you are using to make the measurement and how you use \nthe equipment. If you are measuring the water in the beaker by looking \nat the volume markings, the accuracy of your measurement of the volume \nof water depends first on how you look at the water. That is, are you \nmeasuring at the top or the bottom of the meniscus? (The meniscus is \nthe curved shape of the water's surface caused by its surface tension \nand interaction with it's container. If you aren't sure what this \nmeans, go get yourself an ordinary glass of water and look at how the \nwater curves up where its surface touches the glass.) The second is \nhow accurately measuring lines are painted on the beaker. The third is \nhow thick the measuring lines are: i.e., is it the top, middle, or \nbottom of the measuring line that is the correct measurement?\n\nFor measurements you make in numerous steps that you add together, \neach additional step introduces more error. Let's look at the water in \nthe beaker again. If you have a 500ml (milliliter) beaker, but need 10 \nliters of water in a bucket, you will have to fill the beaker 20 times \nand empty into a bucket. If you consistently put in only 499ml, you \nwould end up 20ml short of water in your bucket. \n\nNow, let's look at measuring distances. If you measure your room with \na professional measuring tape, you will be more accurate than if you \ntry to measure it by laying meter sticks end-to-end. However, if you \nare measuring a real room, you also have to decide where you are going \nto measure it. Most people might measure it on the floor along one \nwall. But is the opposite wall exactly the same length? If you measure \nit at the ceiling, is that exactly that same length? Is the wall \ncurved? (Put your head against a wall and look down a hallway - you \nwill probably see waves and curves in the wall.)\n\nIn short, the term "greatest possible error" has no meaning unless the \nmeasurement method is specified, the error of the measurement method \nwhen done by properly trained people is known, and the people who are \ndoing the measurement have been trained properly.\n\nMy discussion has been based on the assumption that the room is \nreally seven meters long. But what if you are going to build a room \ndesigned to be seven meters long, then measure it. The room is built \nbase on a lot of measurements, so it may or may not be seven meters \nlong before you measure it. You now have more sources of error.\n\nMy discussion is also based on the the assumption that you were \ntalking about measurement error. On thing you have to know \nabout dimensions (e.g., length, diameter, radius, angle, etc.) when \nyou design something is that the dimension always has a tolerance \nstated or implied. That is, if you get a blueprint that says a \ndimension on a machine part is 37.2 millimeters (mm), some place on \nthat blueprint it will say something like "Tolerance for xx.x is \n+/- 0.03." (The "+/-" is read as "plus or minus.") That means that for \na dimension like 37.2 millimeters, you can actually build it so that \nit is anywhere between 36.9 and 37.5 millimeters. Alternately, it will \nbe stated with the dimension as 37.2 +/- 0.03. This means, once again, \nit can have the dimension between 36.9 and 37.5 millimeters.\n\nIf the question really has to do with tolerance, it may depend on how \nyour seven meters is written (i.e, 7m, 7.0m, 7.00m, or even as 700cm). \nIn these cases, you you might reasonably assume that the tolerance is \none-half the last digit. That is, for 7.0 meters, it is +/- 0.05m, for \n7.00 meters, it is +/- 0.005m, for 700cm it is +/- 0.5cm. This \nreasoning implies that 7 meters would have a tolerance of +/- 0.5m, \nbut you have to ask yourself if a tolerance of half a meter in seven \nmeters (about 7 centimeters in a meter) is

Go with a line graph, that way you can also find out (or estimate) temperatures at times when you didnt measure it.

got a dandy.....even though  it  seems  difficult   youll  break through  and  find  out  you can  almost  measure  anything....try  this  because  i dont  know  what  type  of  equipment  you have....in  search  bar  go.....vernier  read .. hit search..the  NTNU site java  is  excellentyou you can  even  practice  measuring  on  line.....reading  a  vernier  is  good too.....check  them  all

as said before it is to prevent mineral buildup inside of the pipes but it is also sometimes used to determine if the pipe is corroding, for example, if you had a large inaccessible iron or steel pipe and you found that the water going into the pipe had a lower concentration of iron than the water coming out, you could assume that the pipe is corroding.

this is very easy, just use the pythagorean therom (i might spell it wrong) the formula is: a^2 + b^2 = c^2 (c is the length of the pipe)\n\n15^2 + 8^2 = c^2\n\n225 + 64 = c^2\n\n289 = c^2\n\n17 = c\n\nyou need 17 feet of pipe

There are some charts on:\nhttp://www.krausco.biz/tonagechart.html\n\nwhich give a tonnage based on several factors. Once you have a method for actually calculating, you could check your answer against this site:\n\nexerpt:\n"RULE OF THUMB formula for making multiple bends on a press brake. For shape shown, in mild steel with radii equal to metal thickness unless otherwise noted.\n\nMultiply Metal Thickness by factor = Tons per Foot\n\nExample for bottom bending\n16ga (.062) Mild Steel. .062 x 150 = 9.3 tons per foot."\n\nHope this helps!

In the American Wire Gauge (AWG) scale, 0000 gauge represents a wire having a diameter of 0.46 inch and 36 gauge represents a diameter of 0.005 inch (5 mils). Diameters for the other gauges are obtained by geometric interpolation, meaning that the ratio between successive diameters is a constant, except for necessary roundoff. Thus n gauge wire has a diameter of .005·92((36-n)/39) inch. The metric wire gauge number is equal to 10 times the diameter of the wire, in millimeters; thus a metric 8 gauge wire has diameter 0.8 millimeters.

You should have a cutting tip (this has one larger hole surrounded by smaller holes). Cutting tips also come in different sizes like the normal tips, so first you have to figure out if you have a cutting tip and which size it is. The size should be written on your tip. And the size of your tip will determine which metal thickness you can cut. I put a link to some website which lists the psi, though I don't know how general this is (I wouldn't go up to 15 with the acetylene, stay safely below that, but then I wouldn't try to cut a 6 inch thick steel plate with a gas torch anyway). You can look around if you find other tables, preferable ones which are for your cutting tip.
