Question

A force of 1.9 [N] is required to move the upper plate at a constant speed of 0.25 [m/s] in a configuration of two parallel, horizontal plates. The area of the playes is 0.5 [m^2] and they are separated by 1 [cm]. (a) Calculate the viscosity of the fluid between the two plates. (b) Calculate the velocity gradient.
