Hallo, does anybody knows where to get friction coefficients for different materials used in design (PTFE; PP; PVDF; PFA; TEFLON; VESPEL) or how to calculate them? Suppliers do not give a lot of data,..is there a theory behind to estimate friction coefficient? thanks in advance!
Question -- phenol and sodium hydroxide
Hallo,
I am searching the kinetic rate constant and the reaction enthalpy for reaction between phenol and sodium hydroxide.
Does sbdy has those two values or knows where to find them?
I tried google science directc etc...
Thanks

Hallo,
I must solve next set of PDE, which presents fluid flow.
dP/dx=d/dx(mi*dv/dx)+d/dy(mi*dv/dy)
dP/dy=d/dx(mi*du/dx)+d/dy(mi*du/dy)
where mi=const
with BC: v=v at x=0
u=u at y=0
Can you give me some hint?
thanks

Hallo,
i would like to make a simulation of some non Newton fluid in a single screw extrudor, what is known alkso as kneader. For solving the equations of motion btw navier stokes in cylindrical coordinates I must solve a set of pde EQUATIONS. i know those three programs, but I would like to...
Hallo.
I am new at forum, could please somebody send me a code for fluid dynamic in 3D written in Scilab, mathematica or Fortran. I will use it to start with learning!b
Thaks,
