A CAPILLARY VISCOMETER DEVICE TO DETERMINE THE FLOW CHARATERISATICS OF NEWTONIAN AND NON-NEWTONIAN FLUIDS

摘要

- The present invention relates to a capillary viscometer device useful for determination of the flow characteristics of Newtonian and non-Newtonian fluid over a wide range of shear rates. The viscometer comprises of an inner cylinder made of heat conducting materials, and an outer cylinder of capacity covered with an insulated sheet, the test fluid being kept in the inner cylinder connected with a manometer by means of capillary being surrounded by glass tube to monitor the pressure in the inner cylinder and the outer cylinder containing constant temperature water bath and the said apparatus is also associated with time monitoring device, stirrer and suction mechanism. It can measure rheological properties of both Newtonian and non- Newtonian fluids continuously including fluids having suspensions and or exhibiting Bingham plastic behaviour.
