Webg) Blow down losses depend upon cycles of concentration and the evaporation losses and is given by formula: Blow down = Evaporation loss / (C.O.C. - 1) h) Liquid/Gas (L/G) ratio. The L/G ratio of a cooling tower is the ratio between the water and the air mass flow rates. Cooling towers have certain design values, but seasonal variations WebBlowdown rate is the percentage of water loss due to blowdown in cooling towers. Generally, the blowdown rate of cooling towers is less than 0.3% of the cooling tower’s water flow rate. So, if the cooling tower has a water flow rate of 730 m 3 /hr (3214 gpm), the amount of water loss due to blowdown is expected to be around 2 m 3 /hr (8.8 gpm). meetup groups palm springs
