Measurement of Pressure between a Rigid Wall and a Compressible Medium by Means off Pressure Cells

摘要

Three types of pressure cells are assessed. The relation between the defluxion of the front plate and the error in registration of the pressure cell is given as a function of the dimensions of the pressure cell and the physical constants for the cell and for the compressible medium. The latter is assumed to be homogeneous and isotropic and to follow Hooke's law.nThe following types of pressure distribution between the pressure cell and the compressible medium are considered:uniformly distributed pressure, axially symmetrical pressure distribution, and arbitrary pressure distribution. These pressure distributions refer to the imaginary state in which the defluxions of the front plate are 0 everywhere.
