%Pasreceived is 5.8±0.008% and %Pdry 12.7±0.008 and %P2O5asreceived 6.63±0.008 and %P2O5dry 14.48±0.008. This shows that there are also other components present in the fertilizer sample that is Introduction The agricultural value of fertilizer samples depend on their total phosphate and water content. Natural phosphates are found in small amounts in all better types of soil and their presence is very important for plant growth. Phosphate content was determined as a precipitate magnesium ammonium phosphate hexahydrate.  Moisture determination is an important indicator of the fertilizer 's quality.
This also supports the hypothesis that molecular weight affects the rate of diffusion. Table 5: Line graph of the diameters of the substances in a three minute interval for thirty minutes Summary and Conclusion According to the experiments made and data gathered, the results strongly support the hypothesis. HCl, having the greater molecular weight, diffused slower than NH3, was closer to the white cloud formed inside the tube than the side of NH3. Potassium permanganate, which has the least molecular weight among the three substances in the agar-water experiment, obtained the largest diameter while the methylene blue, which has the largest molecular weight, got the shortest. Because of these experiments, we can therefore conclude that there is a relationship between the molecular weight and the rate of diffusion.
38 37 CHAPTER 1 INTRODUCTION 1.1 Motivation Materials with small grain sizes have been the focus of attention for scientists and engineers since it has been proved by the work of Hall [Hall51] and Petch [Pet53] that strength increases as we decrease the grain size of the material. This finer grain size also helps in achieving superplastic deformation at higher strain rates and improves the fracture toughness of the material. Some of the traditional methods involving mechanical processes lead to a grain size above 10 µm. In present scenario, some of the techniques also lead to a grain refinement to submicron or nano range like ball milling, vapour deposition etc. But the techniques are not appropriate for large scale applications as they
Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
At the same type of nozzle and feed material concentration, droplet size is decreasing with increasing the atomization pressure (Master, 1991). The feed viscosity and density have a direct relation to droplet size. Increase in viscosity and density of feed means more energy required to break forces in order to have small droplet size. This situation explained in the equation given below: Besides that, the feed surface tension also plays an important role in the level of the atomization. In order to achieve atomization, atomizer should overcome the feed surface tension.

In contrast, high pressure will reduce the formation rate of carbon atoms and the carbon deposition efficiency. In the No. 3 test with a high pressure of 32 GPa and a relatively low shock temperature of 2968 K, only multi-layer graphene was formed without other carbon phases. Appropriate high shock pressures and low shock temperatures are favorable for the synthesis of fewer layer graphene. 4.
In addition to identifying the materials with non-centro symmetric crystal structure, it is also used as a screening technique to identify the materials with the capacity for phase matching. The SHG intensity from the material is measured as a function of particle size. The continuous increase of SHG intensity with the increase of particle size and remaining essentially constant at particle sizes greater than the coherence length confirms the phase matching the behavior of the material [37-39]. A Q-switched Nd: YAG laser beam of wavelength (λ=1064nm) was used with a pulse width of 8ns and the repetition rate of 10Hz. The second harmonic signal generated in the RLHHB crystal was confirmed from the emission of green radiation from the powdered sample.
Feldman and Aboudi10 investigated the buckling of FGM plates subjected to uniaxial loading. It is observed that by using the functionally graded materials, the buckling load improved as compared to the corresponding uniformly reinforced plates. The effect of thermal environment on the supersonic flutter behavior of functionally graded flat panels by using the finite element procedure has been considered by Prakash and Ganapathi11. They highlighted the influence of aerodynamic damping and thermal
