Optimization of Transport properties for the binary system of acetone– water at 303.15-318.15 K by response surface quadratic model. Response surface methodology (RSM) was employed to determine the optimum level of five transport properties of acetone-water mixtures (Densities, viscosities, ultrasonic velocity, refractive indices and surface tension).Central composite design of RSM was applied to study the five transport properties at six levels, and binary mixture (acetone-water) molecular interactions was measured as a response. Regression coefficients were calculated by regression analysis and the model equation was determined. R2 value for transport properties of acetone-water mixture was calculated as 99%, and it indicates that the model was well fitted with the experimental results. Surface plots were made, and the maximum transport properties of acetone-water mixtures (0.85g/cc,0.65m.Pa.s,1540 m/s,1.35 and 74.72 mN/m) was predicted at the optimized values of temperature 318.15K, and mole fraction 0.9. The obtained mathematical model was verified by performing the experiment with the predicted optimized values, and the yield of acetone-water mixture was found to be 8.69 g/L. Validation of the predicted model was fitted 86.9% with the experimental results conducted at the optimum conditions.

INTRODUCTION The thermodynamic, acoustic and transport properties of liquids and liquid mixtures[1-2] are used to study the molecular interactions between the various components of the mixtures and also to understand engineering applications concerning transport processes like heat and mass transfer and fluid flow. In compound and biochemical procedure ventures, materials are regularly dealt with in liquid structure, and as an outcome, the thermo-physical, synthetic and transport properties of liquids accept significance. Therefore, information on a portion of the properties related with the fluids and fluid blends like thickness, consistency, refractive files, ultrasonic speed and surface strain find broad application in arrangement hypothesis and atomic elements [2-3]. Such results are necessary for interpretation of data obtained from thermo chemical, electrochemical, biochemical and kinetic studies [2-4]. Thermo physical, acoustic and transport properties are required in the oil and gas industries for flow assurance and oil recovery [6]. In the chemical industries for the design of separation processes, in the pharmaceutical and polymer industries for solvent selection and emission control but also in the environmental science for the estimation of the distribution of chemicals in various ecosystems and also in biotechnology for the origin of many diseases data are traced to aggregation of proteins and several protein separations [5-6]. Many separation processes in chemical, biochemical and engineering as well as in petroleum industries depend on phase equilibrium data. Depending on the applications and compounds involved, different types of data are needed for example vapour– liquid equilibrium for many distillations, liquid–liquid equilibrium for liquid extractions and solid–liquid equilibrium for crystallization and leaching [6-7]. Optimization of Transport properties for the binary system of acetone-water mixture is a basic advance in bioprocess improvement, and it includes a few variables.[8-16] One factor at a time optimization is accepted method; however, it has numerous weaknesses such as more trial runs and time.[9-20] Response surface method (RSM) is an accumulation of measurable devices to outline and examinations the analyzes concentrated on improvement.[10-23] RSM is effectively utilized to decide the ideal states of the chose factors associated with the procedure.[24-26] The fundamental preferred standpoint of utilizing RSM is to evaluate the participation effect of the components under scrutiny with the help of response surface plots created by the item.

MATERIALS AND METHODS (CH3)2CO was acquired from Merck (India), Bombay and Sisco Research Laboratories (India) of AR grade with immaculateness superior to 99 percent. The Doubly refined water was utilized to get ready arrangement. The blended dissolvable of ACETONE–WATER has been readied utilizing CH3)2CO and water in 1:1 (v/v) arrangement. Eleven arrangements of arrangement from 0.0259 to 1 m focus were arranged and utilized around the same time. The thickness of the arrangement was resolved utilizing pre adjusted Ostwald's viscometer (8-9) including vulnerability inside the request for ±0.067%. The consistency estimations depend on the estimation of stream season of the arrangements taken for the examination with a vulnerability up to ±0.01 s. The thickness estimation has been finished utilizing a bicapillary pycknometer [9-15] with a vulnerability of ±0.06%. Ultrasonic speed of arrangements were estimated utilizing a ultrasonic interferometer [9, 11] (Model F-85) with single recurrence of 2 MHz including vulnerability inside the request for ±0.056%. Refractive file has been estimated utilizing Abbe's refractometer [16-26] with a vulnerability of ±0.062%. Surface pressure was resolved utilizing drop volume tensiometer and the precision of the surface strain assessment was surveyed to be 0.1mNm-1. All the instruments and mechanical assembly were aligned with standard fluids like benzene, 1, 4-dioxane, acetophenone, n- hexane and water before taking estimations. The temperature is kept up steady inside ±0.10C by the thermostatically controlled refrigerated water shower with flowing water around the phone. The weighing was finished utilizing the Denver offset with a vulnerability of ±0.1 mg. 3. RESULTS AND DISCUSSIONS From the ANOVA Table 1, The Model F-estimation of 1225.10 suggests the model is critical. There is only a 0.01% chance that a F-regard this immense could happen in light of upheaval [17]. Estimations of "Prob > F" under 0.0500 show model terms are huge [18]. For this situation A, B, AB, A2,B2 are noteworthy model terms [24]. Qualities more than 0.1000 demonstrate the model terms are not huge [23] . In the event that there are numerous inconsequential model terms (not including those needed to help chain of command), model decrease may improve your model [19]. The "Pred R-Squared" of 0.9886 is in sensible concurrence with the "Adj R-Squared" of 0.9980; for example the thing that matters is under 0.2. "Adeq Precision" gauges the sign to commotion ratio[20]. A proportion more prominent than 4 is attractive [22]. Your proportion of 101.134 demonstrates a satisfactory sign. This model can be utilized to explore the structure space [25]. From the reaction surface diagram as appeared in Fig. 1, it has been seen that with increment in temperature, thickness diminishes and with increment in mole division, thickness diminishes in a sunken upward way [26]. From the R2 esteems it has been seen that the anticipated estimations of thickness is a

The study for the same has been carried on the groundwater by collecting groundwater samples from Vaddeswaram village in Guntur district Andhra Pradesh. In order to develop WQI the samples were subjected to a comprehensive physicochemical and biological analysis of parameters such as pH, turbidity, acidity, alkalinity, fluorides, chloride, electrical conductivity, total hardness, BOD. Geographical information system has been used to map the sampling area. WQI index were plotted from the values obtained by the analysis of various parameters by using empirical method and online software method. The WQI index for the same has been calculated and the values ranged from 53.078 to 293.146. The WQI values from present study indicate the very poor quality water in the area dominated by industrial and construction activities. Poor water quality has been observed in commercial zone of the study area. The analysis reveals the fact that the ground water of the Vaddeswaram needs a degree of treatment before consumption and needs to be protected from further contamination.
