One reason why we study transport phenomena is to gain a better understanding of how to analyze flows in non-traditional systems. An example of this is the flow of chocolate in a chocolate fountain. In this party center piece, the velocity of liquid chocolate has to be slow enough to appear smooth over the fountain's surfaces while providing a conformal coating over them but the velocity needs to be fast enough to prevent the chocolate from freezing onto those same surfaces. To find this perfect point, we need to analyze both the equations of motion as well as the equations of energy. For this exam, we will focus on the equation of motion
