Investigation on functional dependance of adiabatic compressibility of water with varying salt contents and temperature, have been analyzed in the present study. Three water samples distilled (TDS = 06) , Reverse Osmosis (TDS = 74) and Tap water (TDS = 1060) were taken. Factors analyzed were Ultrasonic velocity, refractive index, density and acoustic impedance along with adiabatic compressibility. All three water samples showed variations from usual trend in specific temperature ranges. Ultrasonic velocity showed a minor increase in tap water between (285 – 288K), instead of decreasing, similarly for RO water ultrasonic velocity varied as per comparison with literature review in the range (291K – 294K), and for distilled water ultrasonic velocity showed small variations between (286 – 287K). Density of the three water samples under study, showed a uniform decline with increase in temperature, highest value was observed for tap water 1000.716 kg/m3 and lowest for distilled water 995.706kg/m3. Regression Statistics yielded positive results for correlation between TDS and adiabatic compressibility for Tap water (highest TDS)only, while it showed negative correlation for water sample with low salt content. Further studies on compressibility of water with varying salt content, could pave way for growth of new technology based on the concept of application of compressibility of fluids (specially water).
