(a) Considering a plane Couette flow, the gap between the plates is 1 mm. One plate is fixed and the other is moving at 10 cm/s. If the measured shear stress is 1.34 Pa, calculate the fluid viscosity?

(b) For the same experiment and fluid, what the maximum plate speed to ensure a laminar Couette flow motion.
