Please answer without using previously posted answers. Thanks Let F(x, y) be a two-dimensional vector field. Spose further that there exists a scalar function, o, such that Then, F(x,y) is called a gradient field, and φ s called a potential function. Ideal Fluid Flow Let F represent the two-dimensional velocity field of an inviscid fluid that is incompressible, ie. . F-0 (or divergence-free). F can be represented by (1), where ф is called the velocity potential-show that o is harmonic....

1.1 A flow field describing an atmospheric flow (i.e., a weather pattern) is described by the velocity field V=-Ky2πx2+y2i+Kx2π(x2+y2)j where K=105 m2/s and the x and y coordinate directions are parallel to the latitude and longitude lines, respectively. First, plot the y-component of the velocity when y=0 and -1 km<x<1 km, but exclude the region near the origin (-100 m<x<100 m). What is the x-component of the velocity in this same range? Second, plot the x-component of the velocity when...
