On Practical Gas and Liquid Leakage Diameter Analytic Estimation for Vacuum Applications
This paper presents analytical adaptive expressions for the two distinct cases of tank leakage estimations for gas (sonic and subsonic) and liquid flows under specific measurements data that assists to evaluate a circular hole/slit/orifice (crack) diameter and area. The analytic process is performed by equalization between analytic reformulation of the traditional mass flow formulations and the test formulation for mass flow dependent driven pressure differential over time multiplied by volume. In case of uniform environment conditions, the slit diameter might also represent the total sum of numerous exit holes/slits possible existence. Finally, a qualitative agreement was found between literature and current results in the context of orifice diameter versus pressure differential.
期刊介绍：
WSEAS Transactions on Fluid Mechanics publishes original research papers relating to the studying of fluids. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of this particular area. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with multiphase flow, boundary layer flow, material properties, wave modelling and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
