Bryce DaFonte 10/5/10 BRAE 312 Lab 1 Pressure Measurements The group was divided into four teams, each team being responsible for taking pressure measurements at various work stations at the Cal Poly Water Resources Facility. The first stop during the lab was the natural Gas Engine Pump, which was running at about 750 gpm. We took two pressure measurements as a group and discussed what these measurements meant. The Cornell Pump was then turned on, we measured the pressures in the pipe coming out of the pump, and noticed cavitation was happening. However, to control the process a pump control valve is used, which does not change the pressure reading for the pipe, but eliminates the cavitation problem. Cavitation existed at such a low temperature because the pressures in the pipe were too high, so the water boiled at a lower temperature. Three different flow rates and pressures were recorded at the Cornell Pump, and as the flow rates change, the negative pressures did not, but the cavitation ceased. The next work station was the Collins Tube with the Pitot tube inside the pipe. The
