  1. I'm selling materials that came in handy for me for studying for the PE Environmental Engineering exam. I took the exam in April 2017. They are all in good condition with limited markings. Handbook of Environmental Engineering Calculations by Lee and Lin: $15.00 Fundamentals of Air Quality Systems by Noll: $25 PE Environmental Engineering License Review Manual by Brightwood: $60 PE Environmental Engineering practice exam by NCEES: $30 Practice Problems for Environmental Engineering PE Exam, 3rd Edition by Lindeburg: $60 Environmental Engineering Solved Problems, 3rd edition by Schneiter: $40 Environmental Engineering Practice PE Exams, 3rd edition by Schneiter: 40 Payment can be made by PayPal and I will not charge extra for shipping. If someone is interested in purchasing all of them, I will give a $20 discount on the sum of all the items (i.e. all items for $250!!)
  2. A 10 cubic m storage tank is half filled with water and half filled with air at 21 C. After 88kg (1000 mol) of liquid ethyl acetate (C4H8O2) is added, the storage tank is sealed. Determine the equilibrium concentration of ethyl acetate in water and the equilibrium partial pressure of ethly acetate in the air space. Henry Law constant Kh = 0.3 mol/atm, at 21 C. Please need the basic of chemistry need help.
  3. For those interested, below is a brief breakdown of the new WR/ENV (AM) portion of the exam. The AM portion of the exam focuses entirely on Water Resources (i.e., no Environmental in the morning – at least according to the NCEES breakdown.) I know this change will make a lot of you happy. Below are the topics to be covered during the Breadth (AM) portion of the April 2015 exam: Water Resources and Environmental (17.5% – 7 out of 40 questions) A. Open-channel flow B. Storm water collection and drainage (e.g., culvert, storm water inlets, gutter flow, street flow, storm sewer pipes) C. Storm characteristics (e.g., storm frequency, rainfall measurement and distribution) D. Runoff analysis (e.g., Rational and SCS/NRCS methods, hydrographic application, runoff time of concentration) E. Detention/retention ponds F. Pressure conduit (e.g., single pipe, force mains, Hazen-Williams, Darcy-Weisbach, major and minor losses) G. Energy and/or continuity equation (e.g., Bernoulli) VIII. Site Development (2.5% – 1 out of 40 questions) C. Temporary and permanent soil erosion and sediment control (e.g., construction erosion control and permits, sediment transport, channel/outlet protection) This brings the total Water Resources problems up to 20% for the Breath (AM) exam for – similar to years before. A more detailed breakdown of the changes (including differences between the previous exam specifications) can be found here: I will try to post a breakdown of the depth (PM) changes shortly ... Best of luck to anyone studying for the April 2015 PE exam, Harry
