WebFeb 28, 2024 · System blowdown (BD) rate can be calculated from the following expression: BD= E x ( CR −1) Where: BD = blowdown rate, gpm (m3/hr) E = tower evaporation rate, gpm (m3/hr) CR = concentration ratio or cycles This expression was derived from the following cooling tower water balance relationship: MU = BD + E Webcooling tower performance. Other factors, which we will see, must be stated along with flow rate m3/hr. For example, a cooling tower sized to cool 4540 m 3/hr through a 13.9°C range might be larger than a cooling tower to cool 4540 m3/hr through 19.5°C range. Range Range is determined not by the cooling tower, but by the process it is serving.
