Abstract
In this report the available information on friction factors and leakage characteristics are reviewed and summarized. The use of Pennsylvania State University Mine ventilation simulator (PSU/MVS) to analyze the sensitivity of the ventilation system to the changes in leakage and friction factors are discussed with examples. In simple ventilation systems, the results of changes in leakage and friction factors can be easily solved and explained by the laws of airflow. In complex systems, with fixed quantity branches and multiple sections, the effect of changes in leakage and friction factors cannot be generalized. This study points out the importance of good input data for obtaining reliable information from computer analyses and demonstrates the application of simulators to analyze the effectiveness of ventilation systems. An extensive bibliography on friction factors, leakage characteristics, and ventilation economics is included.
