The aim of this book is to supply valid and reasonable parameters in order to guide the choice of the right model of industrial evaporative tower according to operating conditions which vary depending on the particular industrial context: power plants, chemical plants, food processing plants and other industrial facilities are characterized by specific assets and requirements that have to be satisfied. Evaporative cooling is increasingly employed each time a significant water flow at a temperature which does not greatly differ from ambient temperature is needed for removing a remarkable heat load; its aim is to refrigerate a water flow through the partial evaporation of the same.

Extract: This report critically reviews econometrically estimated export demand equations, multiregion world trade models, including nonspatial and spatial price equilibrium models, and trade flow and market share models. Both single- and multiple-product models are treated. The report describes each modeling approach and its distinguishing characteristics, surveys the recent research, identifies technical and empirical problems, and evaluates its contribution to the objectives of agricultural trade modeling. The report ends with an appraisal of the state of the art and recommends directions for future research and modeling work on agricultural trade.
