Large scale model of Biodiesel factory is coming online.

Today we found that Dr. Olsen is just as excited as we are to get the model working. Yesterday we left the PVC to cure and we found that Dr. Olsen couldn't wait for us, he started the pump to be the first to see it work, NO FAIR!!! He also found the leaks in the fittings that we had to patch before we ran flow tests of the pump. We found that the PSI rate dropped 10 psi after the pump starts, probably the pressure it takes to create cavitation in the pump diaphragm. We started our flow rate at 20 psi and ran 3 time trials to fill a 4000 mL flask. Then we raised the psi 10 and ran 3 tests until we reached 50 psi. At 50 we found that the pump began to flow at 50 psi and dropped to nearly 40 by the time that 4000 mL was reached. Our group figured that this was the psi limit to this pump. We also found that the pump would not function below 20 psi. We also ran some FT IR spectrogram's to test sample purity and prepared samples for the Gas Chromatography machine. Finally we worked out the schematics on our plumbing diagram to divert our flow back to the original container in order to facilitate mixing of Veg oil and the Methanol/KOH solution to create Biodiesel.
