1-1C Thermodynamics deals with the amount of heat transfer as a system undergoes a process from one equilibrium state to
another. Heat transfer, on the other hand, deals with the rate of heat transfer as well as the temperature distribution within the
system at a specified time.
1-2C The de스크립트ion of most scientific problems involves equations that relate the changes in some key variables to each
other, and the smaller the increment chosen in the changing variables, the more accurate the de스크립트ion. In the limiting case
of infinitesimal changes in variables, we obtain differential equations, which provide precise mathematical formulations for
the physical principles and laws by representing the rates of changes as derivatives.
As we shall see in later chapters, the differential equations of fluid mechanics are known, but very difficult to solve
except for very simple geometries. Computers are extremely helpful in this area.
