The list below gives six examples in which tracers are used to visualise the flow. For each of the following scenarios, indicate whether the tracers can be used to approximate (i) streamlines, (ii) streaklines, (iii) pathlines, or (iv) all four.

The flow is laminar but changes with time as the heart beats. f) Magnetic Resonance Imaging (MRI) is used to track a single cell as it moves through the a small blood vessel.

Question 4
The list below gives six examples in which tracers are used to visualise the flow. For each
of the following scenarios, indicate whether the tracers can be used to approximate (i)
streamlines, (ii) streaklines, (iii) pathlines, or (iv) all four. If there is no distinction between
the three types of lines in this context, you should select option (iv).
a) An oil spill, in which oil steady spills into the ocean
b) A small buoy floating freely on a slow stream that is steady state
c) Smoke gradually released from nozzle in a wind tunnel with turbulent flow
d) Smoke gradually released from nozzle in a wind tunnel with laminar, steady flow
e) Magnetic Resonance Imaging (MRI) is used to track a single cell as it moves
through the heart. The flow is laminar but changes with time as the heart beats.
f) Magnetic Resonance Imaging (MRI) is used to track a single cell as it moves
through the a small blood vessel. The flow is laminar and does not change with
time.
