To clarify, we want to determine the speed and direction of oil when spilled when there is current AND wind. We are only using a vector app because of speed, accuracy and ability to use in the field. Looking at the example above, we know from using the app what our magnitude (oil speed) is, what...
We are using a smart phone app to add vectors; once we get the resultant angle, we need to determine what direction the vector is based on the compass. Can someone easily explain how to do this?
Example: Using the app, we input a 2 knot current toward 230 degrees and a 0.7 knot wind speed...
