问题补充：
5km/min怎么换算成m/s
答案：
5km=5000m
1min=60s
5km/min=5000m/60s=250/3m/s
======以下答案可供参考======
供参考答案1:
把5除以3.6
然后把单位换一下就可以啦
供参考答案2:
因为1m/s=1m/(1/60min)=60m/min
所以5km=5000m
1min=60s
5km/min=5000m/60s=250/3m/s
供参考答案3:
5km＝5000m，1min＝60s，则5km/min＝83.3m/s。
供参考答案4:
5km=5000M,1MIN=60S,5000m÷60s=83.333m/s。
供参考答案5:
5000m/60s=500/6 m/s
供参考答案6:
100 CFM x 28.32(换算系数) = 2832 l/min
