Effective area of a strained piston in a piston system with a distorted shape

Conclusions

The solutions obtained above provide, for a known pressure distribution law, a comprehensive analysis of the phenomena in a piston manometer clearance for any pressure in the operating range.

This circumstance in turn can be used in the near future for producing high-pressure reference manometers, and as a substantiated basis for calculating deformation corrections of existing high-pressure piston manometers. The deviations of the latter from a regular geometrical shape are an inevitable consequence of the conditions of their actual deformations under pressure.
