Flow rate: 150.0000 lb/min

  • This is a large industrial flow rate, representative of major process plant streams or large HVAC systems.
  • In metric units, this equals 4082.33 kg/hr, which is the unit most commonly used in European and international engineering.
  • Per-hour rate: 9000.00 lb/hr - useful for shift production and daily batch targets.

Next stepTo find the equivalent volumetric flow rate, divide this mass flow rate by the density of your substance at operating conditions.
