For a fruit juice, shear stresses are measured by a viscometer as a function of
shear rate (the velocity gradient). When the shear stress in N/m2 is plotted
against the shear rate in the range of 0 to 50 s-1, a straight line having a slope of
0.4 is obtained. What is the viscosity of this fluid when the shear rate is 31.4 s-1?
a) 78.5 Pa. s b) 12.6 Pa. s c) 31.8 Pa. s d) 3.97 Pa. s e) 0.4 Pa. s
