Mathematics · Mechanical Properties of Fluids
A block of surface area 0.2 m2 is placed on a frictionless horizontal surface covered with a 0.20 mm thick uniform layer of liquid. On applying a constant horizontal force of 0.010 kgf on the block, it begins to move with a constant speed of 0.075 m/s. Calculate the coefficient of viscosity of the liquid. (Take g = 10 m/s2)
