WebThe basic equations of fluid motion invariably follows the following three step philosophy: 1. Select appropriate fundamental physical principle from laws of physics such as: Mass is conserved. F = ma, Newton’s II law. … WebThe governing differential equation of motion may be obtained using a differential element or by Hamilton's principle. For the present model problem, the result is: (1) where A ( x) = cross-sectional area, E ( x )= elastic modulus, m ( x) = mass per unit length, t = time, u = axial displacement, and x = axial position coordinate.
