Flow rate, the volume of water passing through a nozzle, per unit of time, is clearly an important factor in any spray nozzle. ... the flow rates must be adjusted accordingly using THIS FORMULA HERE.

Put in simpler terms, the mass flow rate is the WEIGHT of the sample, while the volumetric flow rate is the SIZE of the sample. While volumetric flow and mass flow look similar on the outside, Sierra ...

Using English units (pressures in psia, flow rates in MMscfd, areas in sq in., temperatures in °R, and standard conditions of 60° F. and 14.70 psia), it has a value of 0.1549.
