Simplicity of design

Flexible Tube. The simplicity of design and the absence of seals and valves make the flexible tube or peristaltic pump a good choice for low capacity and low pressure appHcations in the pharmaceutical industry or wherever shear-sensitive or moderately abrasive fluids are pumped. Because of the continuous flexing of the tube, the tube material of constmction presents a challenge regarding life cycle. For the same reason, pressures are kept relatively low. 

Centrifugal pumps are widely used in the process industry because of simplicity of design, low initial cost, low maintenance, and fle.xibility of application. Centrifugal pumps have been built to move as little as a few... 

The Sir Galahad instrument takes advantage of the inherent sensitivity of the Merhn fluorescence detector. This detector was originally developed for the analysis of mercury in environmental samples and its principles have been described by Godden and Stockwell [14], Stockwell et al. [IS] have described specific apphcations of the device. It offers a more hnear dynamic range, sensitivity, simplicity of design and the benefits of fiiU automation. 

Wet Wall Electroinertial Precipitator. The wet wall electroinertial precipitator (WWEP) air cleaner was developed to meet the requirements of high operating efficiency, low maintenance, low operating cost, and simplicity of design. To achieve high efficiency with low pressure loss, an electrostatic precipitation was the best candidate method. A wet wall was desirable to flush the precipitate away and to minimize maintenance. Inertial effects were added to assist in moving material toward the wall and to improve the cleaning action of the water on the wall (20). 

The most interesting feature of the decomposition flames is their analogy to flames of the solid monopropellants. In fact, many of these substances, which are ordinarily liquids, may support a flame directly from the liquid phase without auxiliary vaporization of the liquid. In this case, the flame supplies the necessary heat of vaporization or decomposition in exact analogy to the solid propellant flame.8 The principal usefulness of a decomposition flame is found in the simplicity of design and control of a rocket powered by such a flame, even though more powerful fuels are readily available. A recent example, which has been featured in the news, is the hydrogen peroxide attitude-control rocket used in the artificial earth satellites of the U.S.A. 

Flue gas treatment systems can also be classified in terms of the reagent used in the process. Limestone and lime are the two most commonly used reagents for flue gas desulfurization. This is mainly because of the low cost of these reagents, especially limestone. Low reagent costs and simplicity of design make flue gas treatment systems using lime or limestone the most economical of the systems currently available. 

The primary advantages of the batch reactor are simplicity of design, which allows for tremendous flexibility, and integration of the performance equation over time. The simplicity of design, usually a stirred tank, makes operation and monitoring easy for the majority of reactions. The... 

Despite the apparent simplicity of design obtained by the use of a sealed DT generator, practical considerations often lead to less than satisfactory results, and as a result, a considerable amount of ingenuity and skill must often be employed to build a practical unit. Because the use of 14-MeV sealed DT neutron generators, both tagged and untagged, is so common, the details of operation of such systems will be discussed in more detail later. 

Small farm producers continue to use this traditional method because of the low cost of construction, simplicity of design, and ready availability of shell and husk for fuel in coconut farms. 

The primary attractions of SMGs are one handed use, large magazine capacity and simplicity of design which allows for low cost production in small home workshops, without the need to resort to investment castings, milling machines, and other exotic manufacturing techniques and equipment.

Towers with special packings are used and they are characterized by their simplicity of design and operation, stability in work, small hydraulic resistance (300-800 Pa), and a rather small need of energy. In such devices, it is possible to clean gases with initial gas pollution up to 6 g/m3. The efficiency of one step of cleaning for this device for waste gas with pollutant particle size over five microns is usually between 70% and 80%. The disadvantage of this method is that the void volume of the packed tower is quickly blocked by dust, especially at a high initial dust content.
