WebJul 20, 2024 · Figure 28.1: Velocity vector field for fluid flow at time t. We shall introduce functions for the pressure P(x, y, z, t) and the density $\rho(x, y, z, t)$ of the fluid that describe the pressure and density of the fluid at each point in space and at each instant in time. These functions are called scalar fields because there is only one ... WebJun 4, 2015 · For example, a vector field is said to be irrotational if curl = 0, and it is said to be solenoidal if div = 0. These properties of the vector field are useful for analyzing the propagation of seismic waves. Another useful application of vector analysis is to the mathematical representation of fluid flow in two or three spatial dimensions. shirleyj.com
