Fluid Mechanics
流体力学研究流体在静止和运动状态下的力学规律，是机械、能源、航空等专业的核心基础课。内容包括流体静力学、流体运动学、连续性方程、伯努利方程、动量方程、量纲分析与相似理论、管流阻力损失、边界层理论及理想流体势流理论等。学生将掌握流体力学基本方程的建立与求解，能对工程中的流体问题进行分析与计算。
Fluid Mechanics studies the mechanical behavior of fluids at rest and in motion, a core course for mechanical, energy, and aerospace engineering. Topics include fluid statics, kinematics, continuity and Bernoulli equations, momentum equation, dimensional analysis and similarity, pipe flow losses, boundary layer theory, and potential flow. Students master fundamental equations and analyze engineering fluid problems.
给定一个由多段不同直径管道、阀门与弯头组成的供水管网系统，学生需计算各管段沿程阻力和局部阻力，确定系统总阻力特性曲线，根据给定流量与扬程要求完成离心泵选型，并校核泵的工作点与汽蚀余量。需提交完整计算书，包含管网示意图、阻力计算表与泵工作点图。
Given a water supply pipe network with pipes of various diameters, valves, and elbows, students calculate friction and minor losses for each segment, determine the system resistance curve, select a centrifugal pump based on flow and head requirements, and verify the operating point and NPSH. Submit a complete report with schematics, loss tables, and pump operating point plot.
