i dont know too
A Brookfield viscometer is used to measure the viscosity of a fluid. Viscosity refers to a fluid's tendency to resist deformation when pressure is applied to it. For example, honey is a very viscous fluid while water is not very viscous.
E. W. Dean and D. D. Stark in 1920

A capillary flow viscometer, or Ostwald viscometer, consists of a U-shaped glass tube held vertically in a controlled temperature bath. It was named after its inventor, Wilhelm Ostwald.

While measuring viscosity through Ostwald viscometer,diameter of the tube should be small and the flow rate should be slow and steady.
if we put viscometer horizontally, movement of liquid in the tube is not properly and time required by liquid which helps in calculation of viscosity of fluid
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
