Viscosity is a measure of the stickiness of a fluid
Yes
No
Higher viscosity => higher density
True
False
A Newtonian fluid has constant viscosity
True
False
Viscosity = ‘shear stress’ * ‘shear rate’
True
False
Ultrasound can measure Vmax and vessel diameters but not Vave and Area
MRI can measure Vave and Area, but is less accurate than ultrasound for measurements of Vmax
Based on the above, is Ultrasound or MRI more accurate with respect to estimation of stroke volume?
Ultrasound
MRI
They are equally accurate
Assuming fully developed flow in a long circular pipe with an area of A and a maximum velocity of Vmax, which of the following equations is not valid:
Vmean = Vmax/2
Q = Vmean * A
Δp = 4*Vmax2 / 2
