LIQUID SOUND SPEEDS

Liquid Sound Speeds

Note: All the following sound speeds are calculated at 25°C.

The speed of sound in liquids at temperatures other than25°C are calculated as follows.

For every 1°C higher than 25°C take off the value in the Δv/°C- m/s/°C column.

Glycol at 50°C = 1658 - (2.1 x 25) = 1605.5

For every 1°C less than 25°C add on the value in the Δv/°C- m/s/°C column.

Glycol at 5°C = 1658 + (2.1 x 20) = 1700

If the value has a minus sign in front of it then do the opposite of above.

Distilled Water at 50°C = 1498 - (-2.4 x 25) =1558

Distilled Water at 10°C = 1498 + (-2.4 x 15) = 1462
