VT83314 is a compact, multiparameter photometer for measuring key water and wastewater quality parameters. The meter is one of the most advanced photometers available with an innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. Wastewater treatment digestion parameters include COD, Total Nitrogen and Total Phosphorous which are important for monitoring nutrient removal. The VT83314 also offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves.

The VT83224 COD Meter and Multiparameter Photometer for chemical oxygen demand (COD) and specific ion measurement combines accuracy and ease of use in an ergonomic benchtop design. This meter is one of the most versatile photometers in the market, offering 15 measurement methods for different parameters including COD using ready-made liquid or powder reagents. The VT83224 has many advanced features including barcode recognition of sample vials, a graphic LCD to display various chemical forms, and a step-by-step tutorial mode for inexperienced users.

Introduction

Regular arrangement of atoms in molecules and extended solids is very common. In crystalline solids the atoms are arranged in repeating three-dimensional arrays or lattices. Information regarding atomic bond distances and angles is fundamental to understanding the chemical and physical properties of materials. Since atomic dimensions are of the order of angstroms (10 m), unraveling the relative atomic positions of a solid requires a physical technique that operates on a similar spatial scale, Diffraction experiments involving X-ray, electron and neutron sources have therefore played a very crucial role in unraveling these structures. The significance of these experiments in science and engineering courses has been recognized. However, the cost of the equipment and the hazards associated with these experiments have made them very difficult to be

integrated and included in a teaching laboratory setting. The present set-up overcomes these limitations. An increase in scale by thousands from short wavelengths of X-rays to the long wavelengths of visible light, and by hundreds of thousands from an array of atoms in a crystal or an extended solid to an array of dots, allows us to replicate the basic features of a structural determination experiment in a teaching laboratory.

In place of Bragg diffraction whose results are to be simulated, we use Fraunhofer diffraction. Visible laser light passes through an array of scattering centers (dots) on a 35 mm slide. The diffraction pattern is viewed at

what is effectively infinite distance (a meter or so). This arrangement is capable of illustrating many of the essential features of the standard X-ray experiment. Mathematically, the equations for Fraunhofer and Bragg diffraction have a similar functional dependence on the interatomic distance, wavelength and the scattering angle. The symmetry of the diffraction pattern is same as the symmetry of the lattice causing the diffraction.

The central piece of the set-up is a slide (transparency) with eight (A-H) different arrangements of scattering

centers (dots) on different portions of the slide (Figure 3). The examples presented here serve to illustrate how the spacings, symmetries, spot intensities and systematic absences in a diffraction pattern are related to the lattice from which it is derived. Although these are two-dimensional lattices, they mimic what would be observed for diffraction from particular three-dimensional structures that are viewed in projection perpendicular to a face.

Separating Calorimeter:

• It consists of two concentric chambers, the inner chamber and the outer chamber, which communicates with each other through an opening at the top
• As the steam discharges through the metal basket, which has a large number of holes
• The water particles due to their heavier momentum get separated from the steam and collect in the chamber
• The comparatively dry steam in the inner chamber moves up and than down aging through the annular space between the two chambers and enters the Throttling Calorimeter

Throttling Calorimeter:

• It consists a narrow throat (Orifice)
• Pressure and temperature are measured by pressure gauge and thermometer
• The steam after throttling process passes through the heat exchanger and condensate is collected
• There is no need of boiler.

Scope of Experimentations:

• To find the dryness fraction of steam
