Use a caliper that's made for inside measurement.
The cross-sectional area of a tube is equal to the area of the outer circle minus the area of the bore, so using the formula for area of a circle, we can do the following. A = pi*(42/2)2-pi*(26/2)2 = 272 pi, A = 854.513 mm2
The displacement of a 302ci Ford V8 bored 60-over is 310.71ci V v V To calculate cylinder volume you should know the bore and stroke sized of an engine. Say a 350ci Chevy V8 bored 60-over: Normal bore of a 350 is 4" in diameter, so 60-over would measure 4.060" diameter bore. Stroke of a 350 is 3.48". Equation for measuring internal displacement of an engine is: Bore Radius^2 * 3.14 (Pi) * Stroke * # of cylinders = Internal Displacement So using that formula, we would divide of the bore diameter in half to get the radius. Radius is 2.03". Then calculate 2.03 to the 2nd power (2.03*2.03) is 4.1209". Now multiply 4.1209" by Pi which is 3.14. That equals 12.939626". This represents the 2-dimensional surface area of the bore. Now multiply that by the length of the cylinder stroke, which on this engine is 3.48". That equals 45.02989848 cubic inches (cylinder volume). You can round off the numbers to make it more simple, that's fine. Now 45.02989848 is the volume of a single cylinder of that engine. We know the 350ci has 8 cylinders, so we would now multiply by 8 to get the final calculation. The answer is 360.24 cubic inches. I hope this explanation helps a little.
You do a diameter circle!!
It is half of the diameter or radius = diameter/2
The bore is the inside of the barrel- that is, the hole that the bullet is fired through. The diameter of the bore is measuring how wide the bore is from one side to another.
In rifles and handguns the diameter of the bore usually indicates?
Bore slugging is done by taking a lead cylinder(slightly larger in diameter than bore) and pounding it through the bore. Once it's through, you mic it with a caliper. This gives the bore's exact diameter.
I am going to need to bore a larger diameter hole.
The bore of a gun relates to the diameter of the hole in the barrel - and in turn the diameter of the bullet the gun can fire.
diameter of the pipe
The bore of a cylinder describes is measurement, in millimeters or inches, of the inside diameter of the cylinder. The diameter is the width across.
Caliber "Caliber" is a word for the diameter of the bullet or the bore of the gun.
