WebIf a fluid flows in three-dimensional space along a vector field, the rotation of that fluid around each point, represented as a vector, is given by the curl of the original vector field evaluated at that point. The curl vector field should be scaled by one-half if you want the magnitude of curl vectors to equal the rotational speed of the fluid. WebThe vector r(t) is the position vector of the point at time t. Vector point functions are commonly used in physics and engineering to describe the position, velocity, and … Webthe curl of a two-dimensional vector field always points in the $z$-direction. We can think of it as a scalar, then, measuring how much the vector field rotates around a point. Suppose we have a two-dimensional vector field representing the flow of water on the surface of a lake. If we place paddle wheels at various points on the lake, first tech state street salem oregon
