Abstract
The present work highlights the study of effect of temperature variation between (281–303 K) on ultrasonic velocity and adiabatic compressibility for three different water samples, tap water (TDS = 1060), RO water (TDS = 74) and distilled water (TDS = 06). Other factors analysed along with temperature variation and TDS (Total Dissolved Salts) were density and refractive index. 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 (291–294K), 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. Further studies on compressibility of water with varying salts, could pave way for new applications in hydraulics and shock absorption equipment’s.
