Metallic Cartridge Chamber Pressure Measurement

The proper name for this type of measurement is CUP, or Copper Units of Pressure. Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP. Lead is more easily deformed than copper, and the LUP method is normally used for measuring relatively low chamber pressures,...

CUP vs. PSI - Shooters Forum

Mar 13, 2008 · CUP: Copper Units of Pressure. A little steel piston is exposed to chamber pressure and is used to shorten (crush) a copper pellet. The balististian hopes that the inertia of the piston won't affect his measurement. He also hopes the lot of copper pellets is uniform enough to give him good data.

Copper units of pressure - Wikipedia

Copper units of pressure. In the avoirdupois system, the units of pressure are pounds per square inch and in the metric system, the units or pressure are newtons per square meter ( pascals ). A chamber pressure measured with a copper crusher gauge would be expressed as psi (CUP) in the English system or MPa (CUP) in the metric system.

THE COPPER TUBE HANDBOOK - pbar.fnal.gov

(A 2.3- foot column of water creates a pressure of 1 psi.) For example, if 50-50 tin-lead solder is used and the largest tube size is 4-inch at a service temperature of 100°F, multiply 80 (the lower of the solder joint rating of 80 in Table 4 and the tube rating of 257 in Table 3d) by 2.3; the result is 184.

Seawater - Density of seawater and pressure | Britannica

Seawater - Seawater - Density of seawater and pressure: The density of a material is given in units of mass per unit volume and expressed in kilograms per cubic metre in the SI system of units. In oceanography the density of seawater has been expressed historically in grams per cubic centimetre. The density of seawater is a function of temperature, salinity, and pressure.

Missouri Bullet Company

This pressure is measured in "copper units of pressure" (CUPS) and expressed in thousand of pounds per square inch (PSI). The heavier the powder charge, the greater the PSI. Naturally, the purpose of generating pressure in the cartridge case is to force the bullet out of the case mouth and on down the barrel. Lead is a soft metal.

Copper Units of Pressure (Norman Johnson) - Yarchive

Assume two pressure curves having the SAME AREA UNDER THEIR RESPECTIVE CURVES, one with a SPIKED (high "Q") pressure curve, the other with a FLATTER (low "Q") curve. Because the pressures are such that the copper slug is in plastic deformation, the area under the curve is associated with the slug deformation.
