Transfer Phenomena Summary:

Transfer phenomena refer to the study of how mass, energy, and momentum move through different physical systems. It encompasses three main areas:

1. Momentum Transfer:
   Deals with the movement of fluids and the forces involved. It includes concepts like viscosity, pressure, velocity profiles, and Newton’s law of viscosity.
2. Heat Transfer:
   Describes how thermal energy moves between systems. It occurs via three primary mechanisms:

• Conduction (through solids)
• Convection (through fluids)
• Radiation (through electromagnetic waves)

3. Mass Transfer:
   Concerns the movement of chemical species within mixtures. It includes diffusion (Fick’s laws), convection.

These phenomena are interrelated and often occur simultaneously in real-world systems, such as in chemical reactors, heat exchangers, and environmental processes.
