Basic Equations for Flowing StreamsConsider the energy interactions as a stream of material passes in steady flow between points 1 and 2 of a piping system, as shown in Fig. 1.1. From the first law of thermodynamics we have for each unit mass of flowing fluid:

STALE

Compressible Flow of GasesWhen the density change of fluid is small (ρ./ρ. < 2) and the velocity not too high (Mach number, Ma < 0.3), then the mechanical energy balance reduces to the forms developed in Chapter 2. These equations represent the flow of all liquids as well as relatively slow moving gases. This is called ..

Solid Particles Falling through FluidsThe forces acting on a sphere falling through a fluid (call it gas for convenience) are as follows:.In symbols . where the drag force.At the . = 0, in which case equations (8.1) and (8.2) give . The drag coefficient in equation (8.3) has been found by experiment to be related to the particle Reynolds number at terminal velocity, defined as

Unsteady-State Heating and Cooling of Solid ObjectsIf a hot object is plunged into cold water it cools, but not instantaneously. Two factors govern the cooling rate of the object:

Recuperators: Through-The-Wall Nonstoring ExchangersRecuperators are heat exchangers wherein the two fluids transferring heat are kept away from each other by a wall. Their design requires two pieces of information.

Direct-Contact Gas—Solid Nonstoring ExchangersIn this chapter, we first take up the fluidized bed heat exchanger, and then various other devices such as moving grates and moving bed exchangers.
