Falling ball viscometer lab report conclusion
WebAug 28, 2024 · The moving plane has area A and requires force F to overcome the fluid’s internal resistance. The force necessary to move a plane of area A past another in a fluid is given by Equation 2.6.1 where V is the velocity of the liquid, Y is the separation between planes, and η is the dynamic viscosity. F = ηAV Y. Webviscosity of water. This 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.
