摘要
When describing the application of control-volume analysis to linear-momentum-balance problems, students are cautioned that there are two different things to take into consideration when determining the proper sign for the momentum-flux term. This decision can be simplified through reliance on the choice of the coordinate system and control surface to determine the sign.
