When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed.On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular …
WebThe viscosity of a liquid can therefore be defined as the force per unit area necessary to maintain a unit velocity between two parallel planes of the liquid seperated by a unit distance. This mathematically is written as the viscosity is equal to the force per unit area(F?A)(dynes/sq cm) / velocity gradient perpendicular to the planes per second (dv/dx). WebThis was done by using an Ubbelohde glass viscometer (PSL Rheotek, Essex, England) and examining the nature of the viscometer coefficient. Data were collected at 23.5±1.8°C; the mean kinematic viscosity was 0.974±0.078 cSt with a range of 0.969±0.077 to 0.979±0.078 cSt. The theoretical kinematic viscosity at this temperature was 0.927 cSt. …
