(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.The fluid density is 960 kg/m3.
For a sand, the maximum and minimum possible void ratios were determined to be 0.94 and 0.33 respectfully. Find the moist unit weight of sand in lb/ft^3compacted in the field at a relative density of 60%and moisture content of 10%Given Gs=2.65
