WebThis information is useful in dry-cooling system evaluation. The purpose of this study was to present a calculation that would be accurate and simple to implement, and could be applied to evaluate and optimize the thermal performance for hybrid (wet/dry) cooling towers, in which dry- and wet-cooling towers are designed to work in combination. Webphase for the cooling tower located in Jarvis 116. (Assume a packing height of 6 feet) 2. Find the maximum cooling rate (maximum heat load) provided by the tower. 3. Estimate the evaporation rate of water (water loss) for t he tower.
