This lecture covers forced external convection correlations for different geometries like flat plates, cylinders, and banks of tubes, along with the procedure for solving convection problems. It discusses the thermal boundary layer equations, conservation of mass, momentum, and energy, as well as the dimensionless numbers involved in forced convection. The lecture also explores the comparison of velocity and thermal boundary layers, the concept of Prandtl number, and the methodology for calculating convection coefficients. Examples are provided to illustrate the application of convection coefficients in practical scenarios.
