velocity head

基本解釋

Strong radar echoes and positive-negative velocity and head wind area are indicative to the heavy rainfall event.
強雷達回波和正負速度對、逆風區(qū)等特征對強降水具有指示意義。
The liquor is pumped through a large nozzle and the velocity head is utilized to draw the gases to be absorbed into the liquid .
液體用泵送經一只大的噴頭，利用速度變化產生的壓差將待吸收氣體帶到液體中。
Described are the influence of velocity head on the actual flows with same level and the artesian flows for different liquid levels.
指出速度水頭對同一液面高度的實際流量的影響及不同液面高度下的自流發(fā)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
