Get PriceThe 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,...

Get PriceIt's About The Units People seem to think there is some absolute relation between copper units of pressure and the pounds per square inch results of transducer testing. There isn't. CUP is a special unit of measure defined only for ballistic testing; psi is a standard unit .

Get PriceCopper units of pressure or CUP, and the related lead units of pressure or LUP, are terms ... A chamber pressure measured with a copper crusher gauge would be expressed as psi (CUP) in the English ....

Get PriceUnits of pressure are frequently force units divided by area units, e.g., pounds per square inch, dynes per square centimeter, or newtons (N) per square meter. Pressure of Fluids A fluid exerts a pressure on all bodies immersed in it.

Get PriceMar 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.

Get Price(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.

Get PriceSeawater - 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.

Get PriceThis 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.
