CE 321 Lab # 2 Flow Rate Measurement General Info: - Hand in Pre-lab Questions - Worksheet and Spreadsheets due Thursday by 5 pm - Lab Reports due Tuesday by 5 pm (both Hardcopy and Electronic) - www.egr.msu.edu/cee/techcomm Experiment Objectives: 1- to measure flow rates 2- to asses the uncertainty of the measured flow rates 3- to determine how to make accurate flow rate measurements Theory: 1- What is the relationship between volume, time and flow rate? t V Q = (1) If we make measurements of the amount of time it takes to fill a known volume, we can determine the flow rate as seen in Equation 1. Look at Table 1 in the Lab # 2 handout (course pack) 1/5

CE 321 Lab # 2 2- Uncertainty Volume: Taking into account the smallest change in volume that we can reliably identify using our site gauge (hydraulic bench) we can determine the uncertainty for volume. This change is called delta ( ). So the uncertainty in volume is then: δ V = 2 x (229 Time: If we can determine how well we can take time measurements using a stopwatch, then the
