问题烟气在加热炉回热装置中流动，拟用空气介质进行实验。已知空气黏度v空气= 15X10-6 m2/s，烟气运动黏度v烟气=60X10-6m2/s，烟气流速v烟气=3m/s，如若实际与模型长度的比尺λL= 5，则模型空气的流速应为：

选项 A. 3. 75m/ s B. 0. 15m/s C. 2. 4m/ s D. 60m/ s

答案 A

解析

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
