1. Filtered and heated water is converted into tiny water droplets by the sprinklers, which are sprayed on concrete specimens.
2. Water flows into a pre-set underground water tank. When water stored reaches a certain volume, it is pumped to the pipe.
3. Water is filtered by the filter, and flows into the aboveground water tank.
4. Water is heated by the heater and pumped to the upper pipe by the water pump.
5. The cycle starts from Step 1 again.
