Therefore, the formula for flow rate (Q), also known as "discharge rate" expressed in terms of the flow area (A) and its velocity (v) is the so-called discharge equation The resulting Q is the volumetric flow rate. In the case of a round pipe the cross-sectional area is the inner diameter divided by 2 times while if it is rectangular the area is the inner width times the inner height. The equation can bSee more on gigacalculatorFlow in pipe(steel) where is D - internal pipe diameter; q - volumetric flow rate; v - velocity; A - pipe cross section area.
