WebJul 3, 2024 · The viscosity formula is often expressed using Newton 's equation for fluids: F / A = n (dv / dr) where F represents force and A represents area. So, F/A, or force divided by area, is another way of defining viscosity. Dv divided dr represents the "sheer rate," or the speed the liquid is moving. northampton pediatrics patient portalWebNewton’s law of viscosity states that the stress on fluid layers is directly proportional to the rate of shear strain.
