Abstract

This paper explains how to calculate and interpret dimensionless numbers in fluid mechanics for chemical engineering applications, focusing on the Reynolds, Mach, Froude, Euler, Power, Stokes, Weber, Capillary, and Cavitation numbers. The first part presents each dimensionless number individually based on its definition, formula, required variables, threshold values, physical meaning, calculation example, interpretation, and handling strategy. The second part presents integrated case examples to show how several dimensionless numbers can be used together to analyze more complex chemical engineering systems. The examples include pipe flow, gas flow, heat exchangers, slurry pipelines, pumps, valves, nozzles, mixing vessels, wastewater aeration basins, aerated fermentation bioreactors, spray drying systems, cyclones, and particle-laden flows. Through these examples, this paper aims to help readers connect dimensionless-number calculations with process behavior, engineering interpretation, and practical decision-making in chemical engineering.

Abstract

This study examines the integration of nanotechnology into chemical engineering education and its implications for future curriculum development. A bibliometric and technological review was conducted using publications from major scientific databases, with standardized datasets and mapped collaboration and keyword networks to identify pedagogical and curricular trends. The findings indicate a steady growth of interdisciplinary research linking nanoscale concepts with process engineering, accompanied by increasing adoption of virtual laboratories, computer simulations, and intelligent tutoring systems. Nevertheless, challenges remain, including uneven faculty preparedness, limited access to advanced instrumentation, and the lack of unified competency frameworks across institutions. These constraints are largely driven by macro-centric teaching traditions, resource limitations, and inconsistent curriculum standards. To address these gaps, the study proposes targeted updates to core and elective courses that emphasize nano-centric content, sustainability, and digital pedagogy. Overall, the paper presents a practical framework aligned with Safe-by-Design principles and the United Nations Sustainable Development Goals.
