Firstly, find the water flow through the boiler in pounds per hour (lbs/hr). Multiply the water flow rate (in gallons per minute, gpm) by 60 (minutes per hour) and then by the weight of water per gallon ( lbs/gal). For example, if the flow rate is 800 gpm, the water flow through the boiler would be:
