WebSep 5, 2024 · When sizing a sanitary draining system: 1. Determine the flow rate of both boiler effluent and cooling water in gallons per minute (gpm) and add together (as well as any additional fixture load). • Boiler effluent (blowdown) flow rate calculation: The blowdown flow rate needs to be high enough to scour mud and sediment off the bottom … Webblowdown can be a concern. Total water usage is simply drift, blowdown and evaporation. When determining water usage, evaporation and blowdown are the main drivers. Tower drift may also contribute, but it is typically in the range of 0.01% or less of the recirculating water rate and negligible in comparison to evaporation and blowdown.
