| 1 | Measures the rotation part of a velocity field. | |
| 2 | Then, well, let's say that we have such a fluid with velocity given by our vector field. | |
| 3 | The glacier displays alarming signs of increased melt and flow rate. | |
| 4 | Warm winters, however, may allow iceberg calving and high flow rates to continue. | |
| 5 | OK, so we're thinking of F as the velocity and maybe something containing water, a pipe, or something. |
