This experiment investigates the heat transfer characteristics of an ice bag gel phase change material (PCM) incorporated within bricks. The study seeks to investigate the performance of ice bag gel as PCM in improving thermal behavior of building material. The experiment consisted of subjecting brick samples with and without ice bag gel PCM to thermal cycles in a semi-automated laboratory setup. The results indicate that ice bag gel PCM incorporated in bricks exhibited minimal changes and bette...

The purpose of this study is to perform the tensile tests on chicken feather fiber composites to evaluate their potential in practical engineering applications. The study employed the experimental method as a laboratory activity, in which chicken feathers fibers were fused with epoxy resin at different ratios of 5%, 10%, 12% and 14% to form composite specimens. In order to find the ultimate tensile strength, yield strength and the modulus of elasticity of the composites, tensile testing of the c...

This research examines the effect of bricks enhancement with phase change material (PCM) consisting of paraffin on their thermal considerations. The experimental methods were aimed at investigating the mechanisms of temperature transfer throughout the thermal rounds, mimicking diurnal fluctuations of temperature. Due to the high amount of latent heat contained in paraffin a portion of it was transferred into regular bricks with temperature probes tracing the heat processes. It is shown that enha...

This study explores the innovative use of chitosan from shellfish and natural cellulose as an additive to decrease the viscosity of used lubricating oils. We synthesized and applied chitosan and cellulose as adsorbents to filter impurities and enhance the rheological properties of the oil. During the experiment, different amounts of chitosan and cellulose were used, and the Ostwald method was used to measure the viscosity. As expected, adding more chitosan (20 grams) made the viscosity much bett...

The goal of the article is to improve the thermal properties and energy efficiency of the walls and facades of the buildings by introducing the phase change material in the bricks. This study focuses on the thermal insulation capabilities of a paraffin-ice bag PCM mixture, aiming to enhance the thermal inertness of the bricks. The paraffin wax exhibits a high latent heat and is chemically stable, while the ice bags, with their low temperatures, serve as effective thermal regulators. They complem...

This study concentrates on the design and construction of a laboratory-scale centrifuge for the separation of gum from crude palm oil (CPO). The extraction of gum from CPO is essential in the palm oil sector to guarantee that the finished product adheres to quality standards and is safe for consumption. We engineered the prototype centrifuge to accommodate six 600-mL bottles and achieve a maximum rotational speed of 1400 rpm. The design procedure utilised Autodesk Inventor software for CAD model...
