Kraemer Equation
[Sperling-106]
is relative viscosity
- c is concentration. Sperling 106
gives no units. Units should be chosen to cancel with the units of
k".
You could call k" "the Kraemer constant." I
haven't seen any textbook auther give it a name, though.
is intrinsic viscosity.
- The ideas of the Kraemer equation are used to compute
intrinsic viscosity. On a graph where the y axis is the function, the
natural log of
divided by c, and the x axis is
concentration, the y intercept is
. (See
extrapolation to zero.)
- Once
is known,
molecular weight can be determined from the
Mark-Houwink Equation, provided that the constants of the Mark-Houwink
equation, a and K,
are known.
