Module 3: Transport phenomena in furnaces
  Lecture 21: Transport Phenomena in Furnaces: Fluid Flow


For gas flowing substantially at atmospheric pressures in furnaces, flues and ordinary metallurgical equipments, and for liquid flow system mechanical energy balance is very useful. It is

[Mechanical energy input + other energy converted into mechanical energy =mechanical energy output + mechanical energy converted into heat] 
(1)

Consider flow of fluid from point 1 to 2 at steady state as shown in the figure:
