AGA-3 Orifice calculates size, flow-rate or pressure drop for gas and liquid flow orifice meters based on the American Gas Association AGA Report No. 3 (AGA-3) (also API Manual of Petroleum Measurement Standards, Chapter 14.3). Orifice Size is calculated from given flowrate and pressure drop, Flowrate is calculated from given size and pressure drop and Pressure Drop requires orifice size and flowrate. Different taps can be selected: Flange Taps and Pipe Taps. Fluids include gases: Natural Gas (Specific Gravity must be provided), Air and Nitrogen, or liquids: Crude Oil, Water, Methanol, Mono-ethylene Glycol, Diethylene Glycol and Triethylene Glycol. In addition, selecting orifice material will adjust the sizing parameter of the orifice depending on temperature. Customary or SI-units.

Machine learning has become a powerful tool, revolutionizing how industries operate. Unsupervised learning is a machine learning method that analyzes and discovers hidden patterns, structures, or relationships in unclassified or unlabeled data. It is widely used to improve customer experience, provide personalized recommendations, optimize operations, and drive innovation. K-means and DBSCAN are two commonly used unsupervised learning algorithms. Common application scenarios: Customer and market segmentation: Grouping customers based on their behavior, demographic characteristics, or purchase history for targeted marketing and personalized recommendations. Retail analytics: Identifying "hotspot areas" in a store through cluster analysis of customer locations. Cluster2A combines two machine learning algorithms, K-means and DBSCAN, to help users with small datasets take their first steps into the world of machine learning more easily and enjoyably.
