A CAPILLARY VISCOMETER DEVICE TO DETERMINE THE FLOW CHARATERISATICS OF FLUIDS

摘要

A capillary viscometer device to determine the flow characteristics of Newtonian and non-Newtonian fluid which comprises an inner cylinder (1) made of heat conducting materials, and an outer cylinder (2) of capacity covered with an insulated sheet, the test fluid being kept in the said inner cylinder(l) which is being connected with a manometer (14) by means of capillary being surrounded by glass tube (7) to monitor the pressure in the inner cylinder(l), the said outer cylinder(2) containing constant temperature water bath being maintained by a heater (3) and being uniformly distributed by continuous stirring by means of a stirrer and its speed being controlled by a motor (5) , one inlet of the said capillary (12) being connected to the bottom of the said inner cylinder (1), outlet of the said capillary being put to a beaker (13) to determine the flow rate of the lost fluid, the capillary tube being put inside a cylinder containing constant temperature water bath by means of tube (8)&(9) , the inlet of a tube (6) being connected to the said outer cylinder & the outlet (11) being connected to the upper half of the cylinder containing capillary (12), inlet of other tube (9) being connected to the lower part of the cylinder containing capillary (12) & outlet being connected to the said outer cylinder so that the stirrer is placed in the junction of the tube (9) , the said outer cylinder (2) providing the suction mechanism to flow the water inside the cylinder containing capillary (12) to maintain the constant temperature bath.
