velocity head

基本解释

Strong radar echoes and positive-negative velocity and head wind area are indicative to the heavy rainfall event.
强雷达回波和正负速度对、逆风区等特征对强降水具有指示意义。
The liquor is pumped through a large nozzle and the velocity head is utilized to draw the gases to be absorbed into the liquid .
液体用泵送经一只大的喷头，利用速度变化产生的压差将待吸收气体带到液体中。
Described are the influence of velocity head on the actual flows with same level and the artesian flows for different liquid levels.
指出速度水头对同一液面高度的实际流量的影响及不同液面高度下的自流发油流量。

the velocity of a fluid expressed in terms of the head or static pressure required to produce that velocity. It equals /2 where is the density of the fluid and is the velocity. In hydrology the density of water can be written 1/G where G is the gravitational constant
