Path line is the defined as the locus of all the points passed by a particle in a flow field in a given time frame. This is nothing but Lagrangian approach which tracks the motion of individual particles.
Hence b) Lagrangian is correct .
Add Answer to:
Is the pathline associated with an Eulerian or Lagrangian frame of reference? Select one: O a....

131 Consider two observers: O at rest in space (inertial reference frame S), and O' in a noninertial rotating frame, S. S' is rotating relative to S with a time-dependent angular velocity w = 2t î - { +(2+ + 4) Ê. (a) In the rotating frame, a particle has position vector given by r' (t) = (t? + 1)î -- 6th + 4th. Find the true velocity v(t) in reference frame S and the apparent velocity v'(t) in frame...

1. The orientation of a reference frame F2 is obtained from the reference frame F by a 2 - 3 - 1 rotation sequence, with angles Oy, 0, and ex: • A rotation dy about the y-axis of frame F1, • A rotation 0, about the z-axis of the intermediate frame Fi, • A rotation 0x about the z-axis of the transformed frame Ft. (note that we used rotation sequence 3 – 2 – 1 in class to find the...

Problem 1. (15 points) Recall, the Eulerian angles that we defined in class as shown below. The axes (î, þ, â) are fixed in body frame B and the axes (Î, Ê, Â) are fixed in the inertial reference frame F. The orientation of B with respect to mathF is represented through the angles (0, 0, 4) using a sequence about intermediate z, intermediate y and intermediate z-axis again to obtain body-fixed frame B in the final configuration, from the...

1. To model a gasoline spill in a river, emergency responders measure the speed of the leading edge of the spill, while engineers set up a computer model that simulates the velocity field for the entire river. Which of the following is true? a. The emergency responders are using an Eulerian approach and the engineers are using a Lagrangian one. b. The emergency responders are using a Lagranglan approach and the engineers are using an Eulerian one c. Both are...
