One of the simplest pivotal quantities is the z-score.Given a normal distribution with mean and variance , and an observation 'x', the z-score: =, has distribution (,) – a normal distribution with mean 0 and variance 1.
[4] [5] [6] The Kistler ballistic pressure measurement sensor 6215 has a maximum working pressure of 600 MPa (87,023 psi) and is mounted recessed inside the cartridge case (the face of high-pressure sensor does not contact the cartridge case) and requires that the test cartridge case have a hole drilled in it prior to testing. The test ...
An example proofing round for the .50 BMG (12.7 × 99 mm) is the "cartridge, caliber .50, test, high pressure, M1". This uses the standard-weight .50 BMG M1 round propellant (240 gr of WC860), but a bullet weighing 999 gr (+/- 11 gr). The M1 proof round gives a proofing pressure of ~65,000 psi, 11,000 psi (~17%) above the standard service pressure.

In fluid dynamics, aerodynamic potential flow codes or panel codes are used to determine the fluid velocity, and subsequently the pressure distribution, on an object. This may be a simple two-dimensional object, such as a circle or wing, or it may be a three-dimensional vehicle.
