Water was continuously flushed through the system in order to regulate the temperature as well as to compact the soil as much as possible. After determining that all the voids have been removed from the soil, we are now ready to begin the test. In this test, a cone is hooked up to a tube which leads to the inflow nozzle. Another tube that is connected to the water tap allows water to run into the tube. In order to start the test, a constant amount of water must be in the cone at all times.
Water exits the system through an outflow nozzle at the bottom of the flow chamber.
The nozzle is hooked up to a tube which is used to collect water in a graduated cylinder .
