6、量计的使用方法。（5）观察组成管路的各种管件、阀门，并了解其作用。授课内容及方式（1）讲解实验原理；授课方式：利用多媒体教学（2）实验操作演示；授课方式：现场操作；（3）学生自己实验；授课方式：现场指导；（4）学生实验数据处理的讲解；授课方式：利用多媒体教学重点实验原理的讲解要结合教材；学生对实验操作要熟悉，对所要转子流量计、光滑管、粗糙管理解构造与原理难点设备结构与实验操作;注意事项开启、关闭管道上的各阀门及倒U型差压计上的阀门时，一定要缓慢开关，切忌用力过猛过大，防止测量仪表因突然受压、减压而受损（如玻璃管断裂，阀门滑丝等）！实验报告要求（1）在双对数坐标纸

7、上标绘出光滑管、粗糙管的λ~Re曲线，对照化工原理教材上有关公式，即可确定该管的相对粗糙度和绝对粗糙度。根据光滑管实验结果，并对照柏拉修斯方程，计算其误差。（2）根据局部阻力实验结果，求出闸阀全开时的平均ξ值。（3）对实验结果进行分析讨论。思考题（1）在对装置做排气工作时，是否一定要关闭流程尾部的流量调节阀?为什么?（2）如何检验测试系统内的空气是否已经被排除干净?49《化工原理实验》教案授课内容实验二离心泵特性曲线的测定授课对象应用化学专业学时安排4学时目的要求（1）了解离心泵结构与特性，学会离心泵的操作。（2）测定恒定转速条件下离心泵的有效扬程(H)、轴功率

8、(N)、以及总效率（η）
