How do you calculate water loss in a cooling tower?
Cooling tower calculation
- Cooling tower makeup calculation. Water Make Up = D + E +B.
- Evaporation Loss = 0.00085 * 1.8 * C * Δt. C = Circulating water in.
- Blowdown : B = E = Evaporation Loss in.
- COC = Cycle of Concentration.
- Capacity of cooling Tower.
What is blowdown rate in cooling tower?
Before the concentration of these solids becomes too high, some of this water is removed and replaced with fresh water. This process is called blowdown, and blowdown loss is the amount of water lost during the blowdown process in your cooling tower.
Why is 2.4 gpm a ton?
RE: Chilled Water GPM per Ton The 2.4gpm evaporator flowrate and the 3gpm condenser flowrate per ton thumbrules come about due to the increase in heat energy sent to the condenser. The condenser must reject heat from two sources.
What is the formula to calculate GPM?
The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.)
How do you calculate the temperature drop of a cooling tower?
The temperature drop ( ∆T ) for a cooling tower can be measured by taking the temperature of the tower return water (TR) and subtracting the temperature of the basin supply water (TS). This difference can be used to calculate the approximate amount of evaporation that has occurred in the cooling tower: ∆T = TR − TS Recirculation Rate.
How to calculate windage loss of cooling tower?
Drift or windage loss of cooling tower is normally provided by its manufacturer based on cooling tower design. If it isn’t available then you can assume based on below formula. Cooling Tower with drift eliminator: 0.01 * Recirculation Rate / 100
What is evaporation loss in cooling towers?
Evaporation Loss: It is the loss of water from a cooling tower by evaporation. Theoretically, the evaporation quantity of water is 1.8 m 3 for every 10,00,000 Kcal heat rejected. #9. Windage or Drift Loss:
