Unformatted text preview: Rotating shaft viscometer applied a fixed angular velocity to the fluid and the torque required to produce a given angular velocity is a measure of viscosity. At capillary flow method we found viscosities of 45.6 (W/W) % glycerol solutions are 1.778 cP, 1.192cP and 0.838cP at 303K, 323K and 343K. In falling ball method we calculated the viscosities of glycerol solution which are 22.3(W/W) %, 45.6 (W/W) % and 65.6(W/W) % are 2.04cP, 3.16cP and 8.83cP at 298k. Finally with rotating shaft viscometer we observed the viscosity of 45.6 (W/W) % of glycerol solution as 4.17cP at 298K. We concluded that viscosity of aqueous glycerol solution increases with increasing of percentage of glycerol in solution and also decreases with increasing temperature....
