Flow of Incompressible Newtonian Fluids in Pipesl gases, liquid water, and liquids of simple molecules (ammonia, alcohol, benzene, oil, chloroform, butane, etc.) are Newtonians. Pastes, emulsions, biological fluids, polymers, suspensions of solids, and other mixtures are likely to be non-Newtonian. This chapter deals with Newtonians.

Molecular Flowbegin to bounce from wall to wall of the flow channel rather than collide with each other. When this happens the character of the flow changes. Thus, different flow regimes are encountered depending on the value of the ratio.where Kn is called the Knudsen number. These flow regimes are as follows:

PLIC

Flow in Fluidized Bedsentually a point is reached where the resistance just equals the weight of solids. At this point the solids become suspended—in other words, they.become “fluidized”—and the superficial velocity of fluid needed to just fluidize the solids is called the minimum fluidizing velocity ... As the flow rate

Combination of Heat Transfer Resistancesthe wall, (ii) conduction through the wall, and (iii) convection on the outside of the wall. Next, consider a fireplace fire. Here heat reaches the room by radiation from the flames and also by convection of moving air. These processes occur in parallel. There are many processes like these which inv

Heat Regenerators: Direct-Contact Heat Storing Exchangers Using a Batch of Solidsof heat from one gas to another. This requires a two-step operation. In the first step hot gas gives up its heat to cold solids. The solids heat up, and then in the second step, the solids release this heat to a second cold gas. For continuous operations regenerators are used in pairs, as shown in F
