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

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 ..

Non-Newtonian FluidsFluids give and flow under stress. Newtonians are the simplest of fluids, and they are characterized by the property that the velocity gradient at a point is proportional to the shear stress at that point, thus

Flow in Fluidized BedsSuppose we progressively increase the velocity of fluid which is flowing upward through a batch of solids. The frictional resistance increases, and eventually a point is reached where the resistance just equals the weight of solids.
