Pick out the wrong statement.
The shear stress at the pipe (dia = D, length = L) wall in case of laminar flow of Newtonion fluids is 
In the equation, 
the value of 'n' for pseudoplastic and dilatant fluids are < 1 and >1 respectively.
the value of 'n' for pseudoplastic and dilatant fluids are < 1 and >1 respectively.Shear stress for Newtonion fluid is proportional to the rate of shear in the direction perpendicular to motion.
With increase in the Mach number >0.6, the drag co-efficient decreases in case of compressible fluids.
