![]() ![]() Students must know how to use Psychrometric chart to obtain these values for B = 101.3 kPa (very important for exam purpose). The solutions require values like mixing ratio, enthalpy, vapour pressure, specific volume etc. Remember that the mine aerodynamics chapter -normally assumes incompressibility for mine air. Same problem is solved using the three pressure terms of Bernoulli's equation, and also by the concept of Pt,Ps and Pv that are relevant for the gauge and tube pressure survey that is typically conducted in mine ventilation. ![]() The purpose of the file is to help the student appreciate the meaning of different pressure concepts. ![]() Good reference material with lucid explanation and illustrations covering all aspects of ventilation fans ![]()
