Pledge: On my honor, as a student at the University of Virginia, I hereby certify that: 1. The work in this report was written collectively by the members of this group and reflects the laboratory and analysis efforts primarily of this group. 2. The data and other findings of the report are entirely those of this group. 3. The group may have discussed experimental problems during the laboratory with members of other groups or with the TA and may have consulted with members of other groups: where such discussions had significant impact on our work, we have noted the impact and the source of the help in the report using a footnote.

1. Objectives

Objective 1: Calibrate an elbow flow meter.

Objective 2: Determine the useful accuracy and range of commercial flow meters based on vortex generation, magnetic field, and ultrasonic sensing.

Objective 3: Determine the “wheel map” for the centrifugal pump: the relationship between flow rate, shaft speed, and head across the pump.

Objective 4: Determine the pump efficiency of the centrifugal pump as a function of shaft speed and flow rate.

2. Hypotheses

Hypothesis 1: The elbow flow meter will be within 10% of the ASME reference standard orifice sensor reading at varying flow rates.

Hypothesis 2: Using the magnetic flow meter as our base standard, the rotameter, elbow meter,
