82-13: Effect of Altitude on Cooling Tower Design and Testing Drift

82-13: Effect of Altitude on Cooling Tower Design and Testing DriftThe purpose of this paper is to show why altitude is an important factor that should be taken into consideration when designing or testing a tower. Information will also be presented which should be helpful in doing calculations for elevations other than sea level. Only counterflow towers will be discussed in this paper because of the ease in performing the calculations but the principles discussed also apply to crossflow towers.

it only uses common sodium chloride salt as a feed stock

The ability to test the heat exchanger with steam under vacuum rather than hot water makes it unique as well

The tests and results for the analyses are discussed

regulatory officials

pumping head reduction methodology investigated

the water often becomes polluted

There are an infinite number of HP/RPM/shaft combinations that could be requested from a direct drive motor manufacturer

and measure the individual droplets has been a tedious

microbiologically influenced corrosion

Baffles called drift eliminators are placed between the nozzles and the fan to minimize (through inertial impaction) the amount of entrained water droplets that are discharged into the atmosphere

The ISO 9001 quality system can be paraphrased as: (1) Make what the customer wants

During the first days of work it was recognized that any type of refurbishment was not possible
