2. Consider the differential equation, shown below (it is known as Euler equation for steady, 2D, incompressible flow, with negligible gravity effects): u + v 1 POT Here, u and v are velocities in r- and y-directions. (a) Show that the equation is dimensionally consistent (hint: Think of what the dimensions of du and Or will be. They are infinitesimal changes in the quantity) (b) Given the dimensions of each of the terms, can you guess what physical quantity each term in the equation could represent?
