Credit: 7.5 PDH’s (1-Day); 0.75 CEU’s
Instructor: Bobby Rauf, PE, CEM, MBA


Course Description

This workshop caters, mainly, to Engineers, Technicians and Facilities Managers who are not intimately familiar with thermodynamics principles and practices. Through this workshop, attendees are expected to learn or refresh fundamental principles and concepts of thermodynamics in a simple, easy to understand, format; catalyzed by live discussion on the topic in class. This workshop/course illustrates application of thermodynamic principles in practical industrial, commercial and residential applications. This course demonstrates how to analyze and solve various types of practical thermodynamic problems through multiple case studies. In this program, laws, equations, graphs, charts, tables and diagrams, pertaining to various thermodynamics concepts, are covered and utilized in the analysis and solution of the case study problems.
