A flat-bottomed body of contact area A moves with constant speed v over a fixed horizontal surface, with a Newtonian liquid layer of thickness D between them. If the velocity profile in the liquid is approximately linear and the liquid viscosity is η, what is the viscous resistance on the moving body?
