Outlet, location

Normally vessels are designed with the gas outlet location well above TDH. If circumstances force operation with a bed height so that the outlet is below TDH, an equivalent velocity, an effective velocity higher than the actual superficial gas velocity, is used ia the above calculation. The effective gas velocity can be determined from Figure 19 (27). 

In the opposite direction toward each other (e.g., from the outlets located on the opposite walls)... 

Air velocity at any point (X, Y,Z) of the flow created by interaction of two parallel jets supplied from outlets located at a distance 2a from each other (Fig. 7.50) can be described by... 

Typically inlet and outlet locations and heights can be obtained prior to ventilation system design from construction drawings. The static pressure difference across inlets and outlets can be calculated based on the height of the location (Fig. 7.104) and the air density at the respective height ... 

Radial flaw Liquid flowing radially from, or to, an inlet (or outlet) located at the center of the tray, to (or from) downcomers (or inlets) at the tray periphery. 

On the other hand, we can choose an air-to-open valve (+KV) at the outlet location. Now the... 

Chemical enrichment of aerosols. In Figure 4 we plot the relative concentrations of W, V, U, and As in particles collected in stack and at the ESP outlet location with the 8-stage impactors vs equivalent aerodynamic diameter (d5o). 

The nitrator is discharged either through an outlet located in the bottom (Fig. 34) or by forcing the contents out by means of compressed air (Fig. 35). In the latter case the nitrator lid should fit tightly and the fume outlet should also close tightly with a valve. If the nitrator itself has been used as a separator, the spent... 

A schematic diagram of a typical industrial FCC regenerator is shown in Fig. 9.23. The spent catalyst particles are circulated through the regenerator. The orientation, size and location of the spent catalyst distributor are important parameters controlling solids mixing. The regenerated catalyst is withdrawn from the outlet located at the... 

Heating of the model up to assigned temperature at formation pressure of 50 kg/cm. Once the formation temperature and pressure were stabilized at assigned values, the formation liquids were owed to flow out via an outlet located at the end of the model at the opposite side from the steam injection inlet... 

Organic meat is available in approximately 120 sale outlets, located mostly in northern Italy, where 70% of the national consumption occurs. This happens for two reasons (1) a growing interest from operators in the large scale retail (LSR) distribution system where we ean estimate that, in some cases, meat accounts already for 4-5% of total organic food sales and (2) interest from a network of retail shops, who specialize in supplying organie meat. 

First floor services. The aiost frequently used services are steam, compressed air, filtered water, and 110-volt single-phase and 220-volt three-phase current. Outlets for these services are provided at numerous spots on the reactor faces and at two locations on each of. the north, east, and south walls of the building. Sufficient space is available at these outlet locations for future additions. 

The results from the CFD simulation on the spread of the jet by and b of three dimensional wall jets are quite different from the experimentally observed values. Discrepancies also exist for the boundary shear distribution on the wall. Hence, the available software may not serve much purpose in designing the protective work below hydraulic outlets located near the channel bottom. 

Surprisingly, the large variations in concentration that exist do not impact overall module performance. The mixing cup average concentrations calculated from the concentration and velocity fields are nearly identical to the concentrations calculated assuming uniform sweep distribution and no radial variation in the concentration or velocity fields. This fortuitous result implies the inlet and outlet locations for the sweep are not a critical design variable. 

The effect of non-uniform sweep distribution is examined by (1) assuming a Gaussian variation in the sweep flow around each fibre and (2) explicitly calculating the sweep distribution within the bundle for specified sweep inlet and outlet locations. In both cases, non-uniform sweep flows has little effect on module performance. The explicit sweep distribution calculations indicate large radial concentration gradients are present in the module. Surprisingly, these concentration gradients are not detrimental to performance.

The experiment of Kumar et al (2000) consists of continuously feeding the polydisperse suspension through a vertical column in the well-mixed state and allowing the relative motion of particles to exit at an outlet located at a suitable distance from the point of entry. The relative motion of particles will have established a steady state, spatially uniform distribution of particles with an exit number density that can be measured by a device such as a Coulter counter. The population density, / (z, v) in vertical coordinate z and particle size described by volume v, satisfies the population balance equation...
