1.什么叫落差(水头)?水电站或水力站上游的水面总比下游水面高,高出的这一段高度就叫落差,也叫水头或跌差。河道或渠道上游与下游的水面高度差也可以叫落差。在水利工程上多用米作为落差的单位。水头是建水电站或水力站的必要条件之一。2.什么叫流量?流量的意思是指一条河流或一条渠道在单位时间(如一秒钟、一分钟、一小时等)流过去的水量。例如一条渠道每秒钟引进10立方米的水,我们就说它的进水流量是10秒立方米(或写为10立方米/秒),有时说它进10个水。流量多用秒立方米做单位,但是小
1. What is the drop (head)? Hydropower Station or hydraulic station upstream of the water than the downstream surface of the total water higher than the height of this section is called drop, also called head or drop. River or channel upstream and downstream of the surface height difference can also be called drop. In water conservancy projects with more rice as a drop unit. Water head is one of the necessary conditions for constructing a hydropower station or a hydropower station. 2. What is flow? Flow refers to the meaning of a river or a channel in units of time (such as a second, a minute, an hour, etc.) the amount of water flowing past. For example, if a channel introduces 10 cubic meters of water per second, we say that its inflow is 10 cubic meters (or 10 cubic meters per second) and sometimes it says 10. Multi-second traffic flow to do the unit, but small
