摘　　要：针对学生在伯努利方程学习中可能会遇到的问题,采用简单的框图形式对伯努利方程的应用进行了系统的分析,将其应用分成基本应用和扩展应用,其中基本应用包括确定设备间的相对位置、流体流量、管路中压力或压力差、输送设备功率、流体流动方向以及计算阻力损失等,扩展应用包括流量测量和管路计算。本文对学生系统掌握伯努利方程的应用具有一定帮助。As for the difficult faced to students in Bernoulli ＇s equation study, a systematic analysis was made on its application in the form of simple block diagram. The application of Bernoulli＇s equation was divided into basic application and extended application. The basic application included the determination of the relative position between the devices, fluid flow rate,the pressure or pressure difference in the pipeline,the power of fluid transport installation,fluid flow direction, resistance loss, etc. While the flow measurement and the pipeline calculation were included in the extended application. This article would be helpful for students to systematically master the application of Bernoulli＇s equation.
