Poiseuille's Viscosity Apparatus

The Poiseuille's Viscosity Apparatus is a high-precision laboratory instrument developed for determining the coefficient of viscosity of liquids using Poiseuille's Law. Manufactured by Micro Technologies, the apparatus is widely used in physics laboratories, engineering colleges, universities, polytechnic institutes, and scientific research laboratories for fluid mechanics experiments.

The apparatus enables students and researchers to study the flow of liquids through capillary tubes under a constant pressure head and accurately determine viscosity by measuring the flow rate through capillaries of known dimensions.

The system consists of a constant level water reservoir mounted on a sturdy vertical stand, ensuring a uniform hydrostatic pressure throughout the experiment. This arrangement provides highly reliable and repeatable experimental results by maintaining a constant flow condition.

A precision capillary tube is mounted on a rigid wooden base and connected through high-quality rubber tubing. The apparatus includes a graduated measuring cylinder for collecting the discharged liquid and accurately measuring its volume over a specified time interval.

A manometer with graduated scale is provided to monitor the pressure difference across the capillary tube, allowing precise calculation of viscosity. The setup also includes a thermometer for measuring liquid temperature, since viscosity varies with temperature, and a pinch cork for regulating liquid flow during the experiment.

The rigid laboratory construction ensures excellent stability and minimizes vibration, making the apparatus suitable for repeated classroom demonstrations and advanced laboratory investigations.

For enhanced experimental accuracy, optional accessories such as a Digital Stopwatch and Travelling Microscope (Vertical & Horizontal Movement Type) are available.

Every Poiseuille's Viscosity Apparatus manufactured by Micro Technologies undergoes strict quality inspection and dimensional verification to ensure accurate measurements, reliable operation, and long service life.
