About This Product
Darcy's law states that the rate of flow of water through a porous medium is proportional to the hydraulic gradient across it. In this set-up, water is passed through the test section at different flow rates, the flow is timed with the measuring tank and stopwatch, and the pressure difference is read on the manometer. The results are used to calculate the coefficient of permeability. It is taught in civil engineering, soil mechanics and hydrology courses. School Lab Equipment India can export the Darcy's Law Apparatus to education buyers in Slovenia, Cyprus, Burkina Faso, Belize and Luxembourg.
Frequently Asked Questions
Q1. What does the Darcy's Law Apparatus do?
It is designed to verify Darcy's law and find the coefficient of permeability of a given porous medium.
Q2. How are flow rate and pressure difference measured?
Flow rate is measured with a measuring tank and stopwatch. Pressure tappings on the test section are connected to a differential manometer to read the pressure difference.
