"-- imagine parallel steel plates 1 foot apart (top and bottom), with
a fluid in-between-- if the top plate is 1 square foot, the viscosity
of the fluid would be a measure of the force required to slide the top
plate with a velocity of 1 foot per second."
Correction: the top plate does not have to be 1 square foot. The units
for absolute (dynamic) viscosity are FORCE times TIME divided by
LENGTH times LENGTH. We get one of the lengths from the velocity and
the other from the distance apart (plates 2 feet apart, top plate
velocity 2 ft/sec, etc). In SI, abs. vis. would be PASCAL times SECOND
divided by METER times METER. I think centipoise is the absolute times
1000, to get water close to 1.
my apologies,
