How do you read a depth gage?

What kind of depyh gage, Water depth?  If so, they are ussually graduated in feet and fathoms. Tire depth gages are ussually graduated in either 1/32 inch increments or millimeters.  You can look up many types by doing a google search

If you want to measure the volume of sound, it is measured in decibles.\n\nIf you want to measeure the width or band or sound it is measured in Hertz or mega hertz. For this you need an oscilla scope.

Looks like the first answerer has no idea of what you're asking.\n I'll walk you through the math.\n1 atmosphere is equal to 1.01325 bars\nYou get a 1 atm change for every 33 feet in depth. We also have to take into account 1 atm already present at the surface. \n So:\nLets convert the bars to atm's\n20  divided by 1.01325 = 19. 738465 and change.\n That gives you your number of atmospheres equivalent to 20 bars.\n Subtract 1 atm for surface air pressure. This leaves you with 18.738465 atmosphere's to find the depth.\n We know that 1 atm is approx 33 feet in a column of water so \n18.738465 X 33 = 618.369345 feet\n There you go. To get a 20 Bar pressure, you need to be at 618 feet. approximately. Pretty dark down there.\n\nEdit to muddiver.\n \n Appendix C of the USN divers manual contains phone numbers for NOAA and the experimental diving unit, nothing but phone numbers. :)\n What you are referring to is in chapter 2 2-12 table 2-10 and the numbers actually are 33.9139 FW  and 33.066 FSW to a bar in there. I used the standard recreational scuba numbers in my calculations above as they're used more widely and 33 (the accepted standard) is an easier number for everyone to remember and rounded the numbers for the same reason. Also, you forgot to include surface air pressure in your result. That induced an error of an extra atm or 33 feet deeper than the actual result really is. Fine for ultra conservative deco schedules but not the answer he was going for.\n I own the book by the way. :)

look up stuff like static friction, and your coefficient of friction...

Measure the weight of 1 cup of sand and figure it from there.\n\n :-)

Mounting technique has nothing to do with depth. It will allow you to see if the organism is motile because it allows you to avoid staining and observe movement in a liquid. \n\nIf you want to see depth, you're going to need to find either a phase control microscope, DIC microscope, or a TEM imaging microscope. You're more likely to find a phase control than any of the other ones since they run in the millions of dollars and generally scientists don't lend them out.

There are several standards: Brinell uses a ball forced into the metal with a known force, the diameter is then measured and indexed. Rockwell is similar, with the depth being measured. Shores uses a diamond tip hammer is dropped onto the material and the bounce of the hammer measured. Vickers is similar to Brinell but a diamond shape is used instead of a ball. The Monotron Indicator  forces a point into the metal to a determined depth and the force required is measured. Keeps test uses a drill bit to penetrate the metal at a predetermined force and number of revolutions, the depth measured. Each has their own uses in various industries. There are numerous hardness conversion tables to compare the various methods.

Plumb in the vertical and square in the horizontal.\n\nYou can use a square or measurements to determine square in the horizontal plane.  Use plumb bob, or level to determine if it is perpendicular to the ground.  Not sure what you are trying to do.

Determining if your pool is suitable for a diving board is determined by the depth, the slope of the depth, and the distance/clearance of the slope from the diving board. The height of your diving board will also determine if it's suitable.

The best way to find the volume of a liquid is just to put it in a liquid measuring device, graduated cylinder or measuring cup. \n\nFor a solid, a displacement test is good when the shape is irregular. \nex. fill a graduated cylinder with enough water to ensure that when you place the object in the water it will be completly submerged. Note the volume. Place the object in the water, the water level will increase. The amount of the increase will be the volume of the object.

Surveyors have equipment that does that.\n\n If you need a rough # you can stand back and use a fixed item like a person (at that same point) use it as a baseline with a scale measure the person and then measure the tank take the # of time you repeated the scaling and multiply it by your know distance. Its rough but will get you close.

that is not enough information, need to know the density of the soil

Depth perception is a phenomnon where the angular difference between the direction your 2 eyes look is interpreted by the brain as a clue to the distance away from an object being viewed.\n\nThis actually only works up to about 5m distance.  Beyond that, the brain uses 'subconcious trigonometry' (comparing the angular field of an object with nearby or familiar fields) to judge distance.

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.

This property is probably on a canal or some other type of waterway.  Control depth basically tells you the maintained depth of the canal in front of the property for moorage purposes.

I'm not sure what you mean by "Practice 9C" but I guess you are referring to a question number.\n\nI'll just inform you of some stuff anyway. I presume that you are talking about some fluid medium like air or water, and wish to know how pressure varies with depth.\n\nThe relationship you seek is P = hpg\n\nP = pressure\nh = depth under the fluid medium\np = density of medium\ng = acceleration due to gravity\n\nNote that this only holds is:\n1) density is not a function of depth\n2) g is not a function of depth\n\nHence, it is obvious that this only holds over relatively short distances.\n\nThe way that this formula is derived is as follows:\n\nConsider the weight of the medium above the point of interest.\nIf we split into small elements, each of depth dh, then the weight of this element is\ndw = pAgdh\nwhere dw = weight of elemet\np = density\nA = cross-sectional area\n\ndivide by A to get (from the definition of pressure) \ndP = pgdh \n\nNow, we can integrate this to get the pressure as a function of depth:\n\nP = integralFromZeroToh(pg)dh\n\nIf we now assume p = constant, g = constant (here, if we knew how they varied with depth we could include that also)\n\nSo we get \nP = hpg\n\n\nI hope that helps you - email me if you need more info, or if that wasn't quite what you were looking for.
