Nasu, the goal of our measurements is to design an ultrasound camera acoustic lens set for use in cold weather pipe corrosion non-destructive ultrasound measurements. going from pure water to a mix of h20/propylene glycol changes indexes of refraction for ultrasound lenses as the velocity of...

Here are the actual results and graph - attached I appreciate the replies

Nasu, thank you for info, y-axis units are mm/μs, I'll stick the real curve in for your info later, last night I was trying to go from my own recollection of the curve I generated in my lab. GosAtomNadzor

I started with a 100% water sample, and measured the speed of ultrasound using 1MHz transducer, and in 10% increments added propylene glycol to the sample fixture until I reached 100% propylene glycol. Curiously, the velocity of ultrasound waves when plotted against % propylene glycol...
