I would recommend it to anyone who is looking for a solid source to take with them to the test. Also, ask questions! I used the Environmental reference for about 75 of the questions. I felt very prepared going into the exam. Dev. The reason why is because when I took the FE Exam, the only reason I passed was that I was so familiar with the reference handbook. Effective temperature (ET) is the dry bulb temperature at 50% relative humidity, which results in the same physiological effect as the present conditions. I just took the Environmental Engineering PE today (I'm pretty sure I passed, but waiting the 8-10 weeks to know for sure). The PE exam can be difficult. The content, however, is still quite comparable to the paper-based PE exam. Handbook Paul J. Drake, Jr. McGraw-Hill New York San Francisco Washington , D.C.
