hey.

anyone please help me out with the viscosity of
2-methyl-1,3-butadiene and
3-methyl-1-butene.
i have tried google and all but i can seem to locate these values.
thanks

Anything useful in the CRC handbook? What measure of viscosity do you need? What temperature? Is http://www.processcalculator.com/Liquid_Viscosity.aspx good enough?

thanks alot the link was very helpful
an another note do you know of any online friction factor calculator. simple one where you jus have to input Reynolds number and roughness and gives you the friction factor.
i found others that require lots of other data. just need a simple one.
thanks
