The objective of this study is the development of an unsteady flow model of Rheologically complex fluid with fractal structure in various pipe geometries when the pressure is a harmonic function of time at a given frequency at the initial cross section of the pipe. The model was developed using scaling concepts in polymer physics. The obtained results show that the relaxation time and the fractal parameters can significantly influence the process of damping pressure along the pipe. It was demonstrated that depending on these parameters, the attenuation process may increase or decrease compared to the processes in a viscous damping fluid pressure. The results of simulations are compared to those for resin-asphalt-paraffin oils of two types produced in two oilfields.
The objective of the present work is to find out the Influence and optimization of parameters like initial Mn (Manganese) concentration (20-100 mg/l), pH (3-5), and biomass dosage (4-6g/l) of Mn (Manganese) biosorption using the design of experiments by Box-Behnken Design (BBD) in response surface methodology. A total of 15 experiments were conducted in the present investigation towards construction of an empirical model. The optimum conditions for maximum removal of Mn (Manganese) from an aqueous solution were as follows: biosorbent dosage (5.25027 g/l), pH (4.05967) and initial Mn (Manganese) concentration (20.0653 mg/l). At the optimized condition, the maximum Mn (Manganese) removal 2 was found to be 90.3692%. The high correlation coefficient (R =0.989) between the model and the experimental data showed that that the model was able to predict the removal of Mn (Manganese) from aqueous solution using Limonia acidissima hull powder efficiently.
The major contribution of traffic noise, towards overall noise pollution scenario, is a well known and established fact. Traffic noise from highways creates problem for surrounding areas, especially when there are high traffic volumes and high speeds. Vehicular traffic noise problem is contributed by various kinds of vehicles like heavy, medium trucks/buses, automobiles and two wheelers. Many western countries have developed prediction models based on L10, Leq and other characteristics. In India, the transportation sector is growing rapidly at more than 7.50% per annum and no. of vehicles on Indian roads is increasing at a very fast rate. These lead to overcrowded roads and cause various types of pollutions. Amongst these, Noise pollution is an important type which causes annoyance and health problems to human beings.
This paper analyzes the measurement of traffic noise using the Noise Pollution Level, Traffic Noise Index and Equivalent sound levels by the application of noise level meter SL-4023- SD (with a Real Time Data Logger) for a period of 24 hours for up and down streams on a patch of NH-06. The major conclusions obtained are: higher the volume of traffic noise and speed of stream, the value of L10 varies directly.
Biodiesel is the fuel obtained by transesterification of vegetable oil with lower viscosity than vegetable oil. There is lot of generation of Waste Cooking Oils (WCO). Utilization of this WCO leads to low production cost of biodiesel and reduces the disposal problems of waste cooking oils. In the present study, focus is on production of biodiesel using waste rice bran oil o as the raw material through transesterification process. The experimental conditions are selected as 59-60 C as reaction temperature and 300 rpm stirring speed during reaction. The highest yield of biodiesel, 92.02% was obtained at 6:1 mole ratio of alcohol to oil and 0.75% of catalyst concentration and reported as optimum conditions. The concentration of catalyst and mole ratio of alcohol to oil has substantial effect on properties of biodiesel such as flash point, fire point, density and kinematic viscosity. Gas chromatography and mass spectroscopy technique were used to analyze the fatty acid profile of biodiesel sample. The sample contains saturated, mono and poly unsaturated compounds.
Wide spread adoption of Compact Fluorescent Lamps (CFLs) as lighting lamps in residential and industrial sectors are posing challenges to the environment and also carries some health issues and risks. This paper presents a critical overview on related environmental factors and health risks due to lighting lamps especially Fluorescent lamps and CFL. Although CFLs are increasingly popular in the household and industrial lightings due to significant energy savings, however, these issues such as power quality, environment and health risks need to be analyzed critically. The aim of this paper is to make people aware about risks of using FLs and CFLs and not to stigmatize the utilization of these light sources. The CFLs hold very tiny quantities of mercury per lamp. Production plants and disposal facilities of CFLs are releasing mercury to the environment and hence posing environmental challenges that require proper management. In addition, it is found that people working in the CFLs manufacturing facilities suffer from some diseases. Due to the massive number of CFLs used around the world, it is considered as a major source of mercury. If CFLs are not recycled in an ecologically sound manner, after the breakage of CFLs, the inhalation of mercury vapor would cause health risks to human beings, especially infants and children. A detailed discussion on these issues is presented in this paper.
The world of Environmental engineering science is moving at a drastic pace in the midst of immense challenges and scientific vision. Environmental regulations and stringent environmental restrictions have urged the scientific domain to devise newer and innovative environmental engineering techniques. Advancement of science and technology, the wide vision for the future and the wide path towards progress are the torchbearers towards newer realm and newer environmental engineering paradigm. In such a crucial juncture of history and civilization, nanotechnology and application of nanofiltration are of utmost importance. In today's world, nanofiltration and environmental engineering science have an unsevered umbilical cord.
