- Wrote meeting minutes
- Recalibrated the water level, temperature sensor, and flow rate for experiments with vary sizes of sand.
- Reconfigure the Sand Filter Setup to accommodate higher flow rates.
- 4/17: Add the Aerator Apparatus from aeration method to supersaturate the cold water flowing into the sand filter setup.
Metrics
- Process Controller: Instructions for setup was typed up in a Word Doc for anyone to use our setup and run experiments.
- Flow rate measure in Process Controller is not accurate because we altered the flow sensor to acquire a higher range of flow range that can be utilized.
- 4/17: Talked to Monroe about issues of pressure buildup
Outcomes
- Data collected for two different expansion distances in sand suspension for Sand A (size unknown) and Sand 40 (0.42 - 0.59mm)
- Data collected for Sand 40 (0.42 - 0.59mm) is unreliable because during the run, the temperature probe read the temperature over 100C, which is impossible. As a result, cold water was constantly following into the setup instead of a mixture of hot and cold water.
- Ran an experiment with Sand 30 (0.84 - 0.59 mm) which results in a problem for our setup to suspend such large sand size. This error indicates that our setup has a limit to what sand size can be suspended in our setup without causing a buildup in pressure and water overflowing.
