5. comparing the vector values with the average flow rate or directional measurements Flow rates and directions determined by the vector addition programs are obviously vectors Consequently the magnitude of flow will affect the calculated direction If a uniform flow file with steady flow rates and directions 13 were analyzed using both software packages then the direction and rates would be similar However if there is a large variation in the flow direction and a corresponding variation in flow rates then there will be differences For example if a particle is moving due north at 200 um s and a second particle is moving due south at 100um s then the average velocity and direction would show a flow rate of 150 um s in a due east direction respectively The vector addition will show a flow rate of 100 um s in a due north direction There are cases that is if two nonadjacent quadrants contain the highest number of data points then an erroneous reading can results This case however is rare and based on our experience only occurs during swirling flow which is unreliable to begin with The software will note that these files are unreliable for direction determination for the Velocity Vector reading The Well Analysis Summary Sheet has been offered to the user only as an added benefit for determining the True direction and velocity Only a certified Colloidal Borescope Operator should make the appropriate determination of direction and vel
