Question 36
CHMCQ2 marksNeeds review
A student performs a flow experiment with Bingham Plastic under fully developed laminar flow conditions in a tube of radius 0.01 m with a pressure drop (
) of 10 kPa over tube length (
) of 1.0 m. The velocity profile is flat for
and parabolic for
, as shown in the figure.
Consider
and
as the radial and axial directions, and the shear stress is finite as
approaches zero. A force balance results in the following equation
where
is the shear stress. If
is 0.001 m, then the magnitude of yield stress for this Bingham Plastic (in Pa) isYour answerChoose one option.
