Abstract

A gas manifold system is an essential infrastructure in industrial laboratories that distributes gas from storage cylinders to multiple points of use through a piping network. System performance is strongly influenced by pipeline length and the number of fittings, both of which contribute to energy losses during fluid flow and result in pressure drop. Excessive pressure loss may reduce gas supply stability, affect laboratory equipment performance, and decrease distribution efficiency. This study aims to analyze the effects of pipeline length and the number of fittings on pressure drop in a multi-line gas manifold system at PT. X Laboratory, both partially and simultaneously, and to identify the most influential variable. This research employed a quantitative approach using an explanatory observational method. Primary data were collected through field observations and direct measurements using pressure gauges, measuring instruments, observation sheets, and technical documentation. The independent variables were pipeline length (X₁) and the number of fittings (X₂), while the dependent variable was pressure drop (Y). Data were analyzed using descriptive statistics, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination with the assistance of SPSS Statistics software. The theoretical framework was based on fluid mechanics principles, including the continuity equation, Bernoulli equation, Darcy–Weisbach equation, and the concepts of major and minor losses. The findings are expected to provide a scientific basis for evaluating piping network configurations, optimizing gas distribution systems, minimizing pressure losses, and improving the reliability and operational efficiency of multi-line gas manifold systems.
