See in the Journal of the Acoustical society of america. There was an article about ythe sound velocity of water in function of the temperature. It was published almost five years ago. I can find the reference if it's necessary                  Reply  Translate  Close   Martin Schickert R & D, Institute for Materials Research and Testing, Germany, Joined Jan 2000, 18 Martin Schickert R & D, Institute for Materials Research and Testing, Germany, Joined Jan 2000 18 04:09 Jan-06-2000 Re: ultrasonics property of water : I want to get note which is ultrasonics property of water. Bilaniuk, Nykolai; Wong, George S.K.: Speed of Sound in Pure Water as a Function of Temperature J. Acoust. Soc. Am. 93 (1993) 1609-1612 published a 5th order polynomial of the sound velocity of water in the temperature range of 0 to 100°C. The are no remarks as to measuring frequency or dispersion. The classical text Landolt, Börnstein: Molekularakustik (Band 5 der Gruppe II) Berlin: Springer 1967 (in German) shows a similiar polynomial using the older (before 1990) temperature scale. Selfridge, Alan R.: Approximate Material Properties in Isotropic Materials IEEE Trans. Sonics Ultrason. 32 (1985) 381-394 contains tables on temperature dependent sound attenuation in water. Please note the obviously wrong exponential in the respective formula: 10^-7 should read 10^-17. Actual tables are available on the net at http://www.ultrasonic.com/.                  Reply  Translate  Close   marta castillo marta castillo 07:59 Sep-12-2001 Re: ultrasonics property of water i need table with speed of in pure water                  Reply  Translate  Close   Ed Ginzel R & D, - Materials Research Institute, Canada, Joined Nov 1998, 1247 Ed Ginzel R & D, - Materials Research Institute, Canada, Joined Nov 1998 1247 09:11 Sep-12-2001 Re: ultrasonics property of water The Chemical Rubber Co. Handbook of Chemistry and Physics listed the acoustic velocities of water in a table. For distilled water at 25°C it is 1498m/s (density 0.998). For sea water at 25°C (I suppose salinity is related to the temperature) it is 1531m/s and the density of that sea water is 1.025. To establish your actual velocity at the temperature you are working the dV/dT for both distilled and sea water is -2.4m/s/°C Ed : i need table with speed of in pure water .                  Reply  Translate  Close   Product Spotlight Swift & Scorpion2 - a state-of-the-art remote-control ultrasonic crawler StandSilverwing The Swift and Scorpion2 dry-coupled, remote-access ultrasonic crawler bring major efficiency and d ... ata improvements to tank shell inspections and other structures such as vessels and offshore installations. > 4 Showcases4 Videos Research Center IDEKO develops an ultrasonic train wheel inspection system for CAF StandIDEKO S.Coop The Basque Research centre IK4-IDEKO has developed a state-of-the-art ultrasonic inspection system f ... or the train wheel.
