Measuring Liquid Viscosity Capillary Method for Mechanics Physics Lab

This Measuring Liquid Viscosity Capillary Method for Mechanics Physics Lab is designed for determining the viscosity coefficient of liquids using the Capillary Method with an Ostwald Viscometer. The system measures the time required for a liquid to flow through a precision capillary tube under the influence of gravity, providing accurate and repeatable viscosity measurements. An integrated temperature control system allows experiments to be conducted under controlled thermal conditions, enabling detailed investigation of temperature effects on viscosity and fluid behavior. The apparatus also supports capillary action and surface tension studies, making it suitable for fluid mechanics, biophysics, medical physics, and educational laboratory applications.
