thanks again the IAPWS link was great but I could not find any library for this journal.
I think, we have to do some measurements at some laboratory at first.
Thanks a lot @ione.
This graph I was using sins some time now and it´s the only source I know so far which gives such detailed information. Unfortunately not in the range that I´m looking for right now. Extrapolating would be sufficient in the range around 0 °C. But we are narrowing -10 to...
We have to solve a very special pumping problem in an explosive environment.
Can anybody help with data about the viscosity of caustic soda (sodium hydroxide) 20% solution at lower temperatures between 0 and -20°C?
Can´t find any data on the web or in my literature.
Thanks in advance.
