A velocity field is specified as , where a = 2 m/s, b = -6 m/s, and the coordinates are measured in meters. (a) What is the x-component of the velocity field at (2,1/2) in m/s? u = 2 m/s (b) What is the y-component of the velocity field at (2,1/2) in m/s? v = -1.5 m/s The streamline passing through (2,1/2) is given as where c and d are constants, i.e., numeric values. (c) What is "c" in the above relation? c = sqrt(2) (d) What is "d" in the above relation? d = -1.5
