Dividing the volumetric flow by the time, in hours, gives the volumetric flow rate in cubic feet per hour. Dividing the mass flow by the time, in hours, gives the mass flow rate in pounds per hour.Volumetric flow rate is often expressed as cubic feet per hour. Volumetric flow is normally understood as 'volumetric flow rate,' the volume of a material crossing a fixed point in a given amount of time. Mass flow rate is often expressed as pounds per hour. Mass flow is normally understood as 'mass flow rate,' the mass of a material crossing a fixed point in a given amount of time.To convert flows and densities to different measurement units, see the Resources section. For example: a flow rate expressed as cubic feet per hour can be converted to liters per minute or cubic meters per hour. You can convert the result to other measurement units if you wish. If you use a mass expressed in pounds, a density expressed in pounds per cubic foot and a time expressed in hours to calculate a volumetric flow rate, for example, then the result must be expressed as cubic feet per hour. Dividing the volumetric flow by the time, in hours, gives the volumetric flow rate in cubic feet per hour.īe consistent with your use of measurement units in flow calculations.
