Every attempt is made for accuracy in every portion of the guide. It pains me to find mistakes, but I post them here in an effort for complete clarity and most importantly to aid in better exam prep.
I greatly appreciate any and all feedback from users in improving this guide. All of these updates are incorporated for future editions.
2019 PE Prep Guide Errata:
Formula 2.3 (p41): Flame height for wall configurations should use convective heat release rate, not total heat release rate. [ zl=0.166(Qc*/k)^0.4, not zl=0.166(Q*/k)^0.4 ]. This is incorrectly identified in FPH p18-45 Formula (2). NFPA 92 references convective heat release rate and is a recognized, adopted standard.
Formula 8.16 (p79): Temperature inputs should be in Rankine (R), not Fahrenheit (deg F)
Question #156: The question would have to clarify which occupancy is used. Mercantile - Bulk Retail results in a different answer than just Mercantile.
Index (p379): The item "Separation Distance of Storage Tank" at page 263 no longer applies.
