The water solid content has little influence: this table can be applied to raw or
waste water.
When compared with other fluids, the water temperature coefficient for C is
positive up to 74°C. Beyond that, the water becomes a conventional product
again.
The water pressure coefficient is relatively low, at around 0.15 m/s per bar.
The presence of salts as Na Cl in solution increases the value of C by
approximately 1 m/s per g/l.
The addition of glycol ethylene increases also the speed of sound within the
proportions:
For instance: 30% > 1670 m/s and 50 % gives 1705 m/s.
Overheated water involves curve or graph networks taking into consideration P &
T. Consult us.
We give complementary information after on the Cp to take in account energy
measurements.
