The towers included were sized to cool 4540 m3/hr through a 16. These towers rely on an exchange of heat between the machinery, the water in the tower, and the air passing through the tower. Recommendations by manufacturers regarding cleaning schedules are, therefore, to be recognized as merely guidelines. For example, under earthquake acceleration the riser will respond at high frequency and low amplitude, whereas the tower structure (of lower modulus material) will respond at lower frequency and greater amplitude. The overall width of all towers is 21. Therefore other design parameters are also needed.Balises :Wet-bulb TemperatureCondensersDraft Wet Cooling Tower Cooling a stream of water to a lower temperature using evaporation does this.
