How do you calculate the flow rate of a cooling tower?
Heat Load (BTU/Hr) = GPM X 500 X ° Range of cooling, or rearranged to determine the design flow rate. GPM = Heat Load (BTU/Hr) = 6,250,000 Btu/Hr = 835 gpm 500 X ° Range of cooling 500 x 15° R Now you can make your cooling tower selection based on 835 gpm, cooling from 98°F to 83°F @ a design 76°F Twb.
How is cooling tower energy calculated?
Cooling Tower Thermal Efficiency Calculations
- Approach = Cold Water Temperature – Wet Bulb Temperature.
- Range = Hot Water Temperature – Cold Water Temperature.
- Cooling Tower Thermal Efficiency = Range/ (Range + Approach) x 100.
- COC = Silica in Cooling Water / Silica in Makeup Water.
How is cycle concentration calculated?
It can be estimated by dividing the conductivity of the system water by the conductivity of the makeup, or by dividing the chloride of the system water by the chloride of the makeup.
What is cycle of concentration in cooling tower?
A key parameter used to evaluate cooling tower operation is “cycle of concentration” (sometimes referred to as cycle or concentration ratio). This is determined by calculating the ratio of the concentration of dissolved solids in the blowdown water compared to the make-up water.
How do you calculate blowdown in a cooling tower?
It is calculated by this equation:
- Evaporation loss = 0.00085 Wc (T1-T2)
- Drift loss = 0.02% water supply [for new development in eliminator design]
- Blowdown = [ Evaporative loss – (COC – 1) x Drift loss] /(COC – 1)
What is ORP in cooling tower?
ORP is a measure of a solutions oxidizing or reducing strength. The chemical way to look at redox processes is that the reductant transfers electrons to the oxidant. Thus, in the reaction, the reductant or reducing agent loses electrons and is oxidized and the oxidant or oxidizing agent gains electrons and is reduced.

How do you calculate the evaporation rate of a cooling tower?
concentration of liquid in cooling towers according due to evaporation that cools the water….Cooling tower calculation
- Cooling tower makeup calculation.
- Evaporation Loss = 0.00085 * 1.8 * C * Δt.
- Blowdown : B =
- COC = Cycle of Concentration.
- Capacity of cooling Tower.
How to calculate tons of cooling for a cooling tower?
Calculating the tons for a cooling tower requires you to understand some basic information about it works. Calculate a ton of cooling load using this formula: Cooling load = 500(1 US gal/min)(10 degrees Fahrenheit)/12,000_._ A 1-ton chiller is equal to 12,000 British thermal units. This amount of heat could theoretically melt 1 ton of ice in 24
How is the thermal calculation of the cooling towers?

How much water should be in your cooling tower?
Typically, 6,000 hours a year will have a wet bulb of 60°F or lower, meaning that a cooling tower cell designed for a 78°F wet bulb will be able to make 65°F -67°F water for 6,000 hours per year nearly 70% of the year. Most cooling towers are capacity rated at a “standard” wet bulb temperature of 78°F. That means on the days when the wet
How do you calculate water loss in a cooling tower?
Evaporation loss = 0.00085 x 10 000 x (100-85) = 127.5 gpm.
