Question

After calibrating a test anemometer against a standard in a wind tunnel, you obtain the following mathematical function that relates the test anemometer wind speed values, Va, to the "true" standard wind speed, Vs: เสี Vs AVaB, where A 1.02 0.03 and B 0.3t 0.1 ms1. By examining the standard deviation of Va at several different wind speeds you also estimate any individual Va value has an uncertainty of 0.3 ms 1. The mean measured wind speed, Vawas 3 m/s. Given the uncertainties in A, B, and individual Va, which of the three has the largest impact on the total error? 1.1
