Pressure Measurement
Pressure Measurement
(OP)
Hi ,
Could you guide me about this problem?
I want to calculate max pressure in the capillary rheometer.And then I will calculate outher diameter of barrel and die for safe.But I can't find true formula for this aim.Max piston load ,barrel diameter die diameter and max-min shear rate values are known but I think P=F/S is not enough for calculate pressure because of viscosity ,shear rate etc.
How can I calculate max pressure in barrel and die?.
Thank you so much your interest.

RE: Pressure Measurement
s=pd/2t
where
s=tensile stress in wall
p=pressure
t= wall thickness
d= diameter of cylinder
