What is the viscosity of water at 25 degree express in centipoise.?
I have checked a number of references, but finding the value at 25°C has been difficult. The best I could do is: The viscosity of water depends on temperature. At 293 K (20°C), the viscosity of water is 1.002 cP. Its viscosity decreases as temperature increases. I found that all the references are to water having a viscosity of 1.002cP at 20°C. So you can be confident of this. It seems that at 25°C the viscosity will be 0.891cP. (1 reference only) Incidental, the SI unit for viscosity is the Pa.s which is numerically equal to the poise. cP will therefore be mPa.s (milliPascal seconds.
