Velocity Triangles Analysis vs Carbon Compounds Practice

VTA app is a velocity analysis application of a turbomachinery stage. The user can easily extract useful results and velocity diagrams by importing some dimensionless sizes, input-output angles and general geometric features. This application gives also the ability to compare cases with different input parameters. Through a quick and easy analysis of the velocity triangles inside a turbine or a compressor the student could experiment and thus gain a deeper understanding of the operation of an energy system. It has been developed for education purposes.

Carbon Compounds Practice is an educational application designed to help students prepare for NEET and JEE examinations through structured practice in organic chemistry concepts related to carbon and its compounds. The app provides chapter-wise quizzes, mock tests, and daily practice questions aligned with competitive exam syllabi. Students can solve conceptual and numerical problems, attempt mock tests for assessment, and monitor performance using statistics. The app supports systematic revision of key organic chemistry topics frequently asked in competitive examinations. Topics Included 1. Covalent Bonding and Tetravalency Covalent bond formation, tetravalency of carbon, electron dot structures, single, double and triple bonds, catenation, bond length and bond energy. 2. Classification of Hydrocarbons Alkanes, alkenes, alkynes, aromatic hydrocarbons, general formula relations, and hydrocarbon numerical problems. 3. Nomenclature of Organic Compounds IUPAC naming rules, parent chain selection, carbon chain numbering, functional group priority, common naming systems, and nomenclature practice problems. 4. Functional Groups and Their Reactions Alcohols, carboxylic acids, aldehydes, ketones, halogen derivatives, ester formation, and functional group numerical problems. 5. Chemical Properties of Carbon Compounds Combustion reactions, oxidation reactions, addition reactions, substitution reactions, esterification reactions, and reaction mechanism-based problems. 6. Homologous Series and Isomerism Homologous series concept, variation of physical properties, structural isomerism, chain isomerism, position isomerism, and isomer counting problems. 7. Carbon Compounds in Everyday Life Ethanol properties, ethanoic acid properties, soaps and detergents, micelle formation, hard and soft water, and numerical problems related to cleaning agents. 8. NEET & JEE Advanced Focus Hybridization of carbon, bond angle prediction, degree of unsaturation calculations, reaction mechanism concepts, assertion–reason questions, and commonly tested competitive exam topics. Key Features Chapter-wise practice quizzes Mock tests for full syllabus assessment Daily quiz for regular revision Performance statistics to track accuracy NEET & JEE aligned organic chemistry syllabus Simple and distraction-free interface Carbon Compounds Practice is suitable for students preparing for NEET and JEE who want structured practice in hydrocarbons, functional groups, organic reactions, and nomenclature concepts.
