Convection & Dimensionless Numbers EXPLAINED | Reynolds, Prandtl, Nusselt, Grashof, Rayleigh

Welcome to Academic Engineering! This is the most complete and practical lecture on Convection & Dimensionless Numbers for engineering students, mechanical engineering, thermal sciences, and heat-transfer learners. In this video, we explain both forced and natural convection, followed by mastering five essential dimensionless numbers used in fluid mechanics and heat transfer: ✔ Reynolds Number (Re) ✔ Prandtl Number (Pr) ✔ Nusselt Number (Nu) ✔ Grashof Number (Gr) ✔ Rayleigh Number (Ra) You’ll understand their physical meaning, formulas, and engineering applications. After the theory, we go into FOur FULLY SOLVED EXAMPLES, including: Flow regime identification Calculating Reynolds number Using Prandtl for thermal properties Finding Nusselt numbers from correlations Finding heat transfer coefficients (h) Natural convection using Gr and Ra These examples are exactly what engineers solve in HVAC, automotive cooling, thermal design, and industrial heat exchangers. 🎯 Who is this video for? Mechanical Engineering students Thermal engineering learners Heat Transfer, CFD, HVAC, and Fluid Mechanics students Competitive exam preparation Engineers wanting a refresher 🌟 If you found this helpful: 👍 LIKE the video 🔔 SUBSCRIBE for more engineering lectures 💬 COMMENT your topic request!
