CHAPTER 7 Heat Exchanger discuss heat transfer from flowing fluid to a solid wall Heat transfer coefficient ? depends upon the flow velocity (u),
Flow around cylinders and spheres is characterized by boundary layer development and separation • Heat transfer coefficients are strongly influenced by the
Mostly, the convection coefficient stabilizes for a tube beyond the fourth or fifth row ? In general, heat transfer enhancement is favored by the more

When the temperature of something is increased the particles have more energy and move more rapidly • Heat is the transfer of energy between objects
