SPREADSHEET FOR DATA ACQUISITION AND REDUCTION LAB3 - Measurement of pressure distribution and forces acting on an airfoil Table of Contents Color code: Sections 1. Experimental Summary Comments 2. Data reduction equations Enter experimental data 3. Data Acquisition and Reduction Calculated/output value 3.1 Input variables Data Given 3.2 Measured variables Instructions 4. Uncertainty Analysis 4.1 Bias Limits Both Cp and Cl need to be plotted along with the benchmark data on the same graph. 4.2 Precision Limits Example plots for both pressure and lift coefficient along with the benchmark data 4.3 Total Uncertainty are shown below. 1. Experiment summary Statement of Purpose: The purpose of this spreadsheet is to facilitate data acquisition, reduction and uncertainty analysis Facility: Vertical Wind Tunnel (WTA) Test Design: Airfoil set in the test section of the wind tunnel Semester of tests performed: Spring 2004 References: Lab3 Handout: .edu/~fluids/Lab/EFDLab3.PDF, 2.
