The fluid in a certain period of time through a cross-sectional volume or weight called flow. Using the volume that the flow unit is L/s or
( `m^3`/h ); with the weight of said flow unit is kg/s or t/h.
Fluid flow in pipes, in a certain period of time, the flow velocity of flow distance, generally refers to the average flow speed of the fluid, the unit for
M/s.
Flow and pipe section and velocity is proportional to, the relationship between the three: high official valve limited company provide
= ( QΠ D^2 ) / 4 · V ·3600 ` ( `m^3` / h )
Type Q - flow ( `m ^3` / h or T / h );
D - pipe diameter ( m );
V - mean velocity of flow ( M / s ).
