1 In many fluids, the flow velocity is observed to vary linearly from zero at the bottom to u at the top. Moreover, the magnitude F of the force acting on the top plate is found to be proportional to the speed and the area A of eaclh plate, and inversely proportional to their distance separation y The proportionality factor μ is the viscosity of the fluid. Using the above equation find out the dimensions of (10 pts.) A car...
