Viscosity: kinematic to dynamic
Viscosity: kinematic to dynamic
(OP)
hello again,
does anyone know how you would convert 450centistokes kinematic velocity into a dynamic velocity???
many thanks

RE: Viscosity: kinematic to dynamic
Dynamic viscosity = kinematic viscosity x density
Other useful stuff:
1 cSt = 10^-6 m2/s
1 cP = 10^-3 Pa.s = 10^-3 kg/(m.s)
So, for water at 20°C:
Dynamic viscosity = 1 cP = 10^-3 kg/(m.s)
Kinematic viscosity = 10^-3 kg/(m.s)/1000 kg/m3 =
10^-6 m2/s = 1cSt
RE: Viscosity: kinematic to dynamic
1 cP (centipoise) = 0.001 kg/(m.s)
1 cS (centistoke) = 0.000001 m2/s
The only requirement for the conversion is that the temperature for measuring the density should be the same as that used for measuring viscosities.

6.72*10^-4* Value(centipoises)= 6.72*10^-4*value (lbm/ft-sec)
6.72*10^-4*value (lbm/ft-sec) /[rho(lbm/ft^3)]=
6.72*10^-4*value/rho (ft^2/sec)

I have written a utility program called "Uconeer" that will do many conversions for viscosity. It can convert a dynamic viscosity from one set of units to another, and similarly for kinematic viscosity.
It also includes a calculator to convert between dynamic and kinematic viscosities by entering the density. It is very flexible because you can select whatever units you want for each of the viscosities as well as for the density.
This is a freeware program and can be downloaded from

I recently saw your conversion tool upon mentioning by Phex two threads below. It's a nice program and you really did a good job.
PS: I generally use Convert It whenever I get bored of doing manual conversion.

good work, and thanks for sharing it to all of us.

Thanks for your kind words about Uconeer. I can't allow my bias to show through by telling everyone about my software, so I appreciate it when people like you do it. I'm sure others would much sooner believe a neutral person than the author of a program.
I always think we software authors are like new mothers - our babies (ie programs) are the most beautiful in the world (in our eyes)!
Quark, I would appreciate your views on why you prefer to use Convert It (which is a very good program) rather than Uconeer. I am always keen to find out what other people really want/need/enjoy in programs.
regards
Harvey
