NCEES PE Mechanical HVAC Practice Exam Problem 13 - Chilled Water System (Solution Tips)

I made this video to clarify issues with the NCEES solution for PE Mechanical HVAC & Refrigeration Practice Exam Problem 13. The NCEES solution is very confusing. First, the problem says both the AHU-3 and the system bypass are at the same level, 75 feet, which doesn’t correlate with the given figure and isn’t needed anyway. Second, each AHU and it control valve are in parallel with the rest of the system, so the pressure drops must be equal. The rest is converting a pressure head to pressure. Give this problem a try, then watch the video, and let us know if you find it helpful. - Dr. Tom (AKA Dr. Thomas H.
