An Introduction to Agricultural Engineering: A Problem-solving ApproachThis thoroughly revised and updated second edition introduces readers to the basic principles involved in agricultural engineering and the typical problems inherent in managing the two biggest resources in any agricultural enterprise - land and mechanical devices. Air conditioning and refrigeration, materials handling, and wind and water erosion are some of the new topics that are featured. Emphasis throughout the book is on problem-solving techniques. For each topic, the authors provide basic principles and technical information and then present readers with a unique problem-solving approach. The book includes practice problems, along with necessary tables, conversion values, and equations, to aid understanding of complex problems. |
