ELASTIC PRESSURE DISTORTION OF THE VOLUMES OF A 1,000-ATMOSPHERE BURNETT COMPRESSIBILITY APPARATUS OVER THE TEMPERATURE RANGE 0TO 75C.

摘要

A removable-jacket distortion apparatus was constructed and used to measure distortion coefficients for two high-pressure vessels. The measured distortion coefficients were used to compute distortion coefficients for volumes V1and (V1+V2) of a 1,000-atmosphere Burnett compressibility apparatus for the temperature range 0to 75C. Young's modulus for Armco 17-4PH stainless steel,heat treated to condition H1150-M,was computed from experimentally determined distortion coefficients. A 10-to 14-percent correction to the values obtained for Young's modulus may be required because pressure vessel end effects were neglected. The distortion coefficients of the compressibility apparatus are believed to be accurate to about 1percent. (Author)
