Consider the following statements regarding Hydrostatic and hydrodynamic lubrication,

1) In Hydrodynamic lubrication, there is no need for a pressurized supply of lubricant.

2) In Hydrostatic lubrication, surfaces do not contact during the rotation as there is a thick film of the lubricant.

3) Starting friction is low in hydrostatic lubrication.

Which of the above statements are correct?
