Abstract<\/strong><\/p>\n\n\n\n

This scientific paper aims to conduct an experimental investigation into the characteristics of a centrifugal fan operating at a constant rotational speed. The focus will be on measuring and analyzing the volumetric flow rate of the fan at this fixed speed, while also examining variations in the cross-sectional area of the discharge duct. Furthermore, the paper addresses the relationship between pressure and discharge area, as dictated by the principle of the Bernoulli’s equation addition to the correlation between discharge area and fluid velocity, as described by the continuity equation. Consequently, this study encompasses the key relationships and theories within the field of fluid dynamics. Graphical representations illustrating the fan’s characteristics as a function of its flow rate are presented, and the relationship between torque and the prevailing operating conditions surrounding the fan is also observed. Through this investigation, we seek to gain a deeper understanding of the fan’s performance under various conditions.<\/p>\n\n\n\n

The utilized apparatus serves as an experimental platform enabling the study of the fan’s behavior and the measurement of its diverse performance characteristics. This setup allows for the analysis of the impact of fan blade design, pitch angle, and the influence of obstructions in its vicinity on the flow rate, generated pressure, and energy consumption efficiency.<\/p>\n\n\n\n
