WebMay 1, 2024 · Some examples of terms are 7, y, 5x2, 9a, and 13xy. The constant that multiplies the variable (s) in a term is called the coefficient. We can think of the coefficient as the number in front of the variable. The coefficient of the term 3x is 3. When we write x, the coefficient is 1, since x = 1 • x.

WebThe flow rate of the fluid across S is ∬ S v · d S. ∬ S v · d S. Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube.
