kinematic viscosity

[chemproject]

How do I convert from cSt to redwood seconds. I have kinematic viscosity = 1.20cSt at 40C, and I want to convert to Redwood 1 seconds.

you can find a table ranging from 1 to 21600 cSt here:

.
you should be able to interpolate from this one for a reasonably precise number.
so far, I haven't found any conversion formula in my documents, but i will update as soon as and if i find it.

hth,

From the net:

Redwood I, s cSt

29 1.0
29.4 1.13
29.8 1.81
30.2 2.0
30.6 2.11
31.3 2.4
32.1 2.56
37 4.5
55 11
86 20


For 1.2 cSt you'll need to interpolate. There are plenty of conversion tables for KV above 2.0 cSt, some supplied free by pump manufacturers.
