Book Description
Lumpy Water Math was written to help wastewater treatment plant operators and collection system operators with the basic problem solving ability needed to evaluate and control these systems. This understanding will help the operator use math in day-to day operation as well as help prepare for certification exams. The math will be helpful to water supply and distribution system operators as the math used is basically the same.The instruction begins with basic instruction in solving for areas and volumes, detention time, flow calculations, hydraulic and organic loading and progresses to specialty areas such as activated sludge and laboratory calculations. The book includes tips for making problem solving and use of calculators easier. Typical state design standards are listed so that problem answers can be compared to accepted values. The book includes many practice problems with answers given in the appendix to help operators become proficient in basic problem solving.

Book Description
Watermaths presents the mathematics underpinning the design and operation of the individual unit process technologies used for purifying water and wastewater. The book aims to provide the reader with sufficient information to enable them to tackle the most important calculations in this area, without requiring any prior knowledge of the subject and assuming only a very basic grounding in science or engineering. It focuses on the most essential areas of knowledge required, containing tuition in basic numeracy, chemistry, process engineering and fluid physics, as well as cost analysis. The simple and succinct delivery is designed to get the reader up to speed as rapidly as possible: sufficient background information is provided to explain the purpose of the calculations, and ultimately tackle the complete wastewater reclamation plant design problem included in the book. Example calculations are provided within each chapter, each followed by exercises intended to reinforce the learning (and for which solutions are appended). Exercises range in difficulty from simple single calculational-step problems to more complex ones, and the over-arching design problem provides some context to the mathematics. The book can be understood by those relatively new to the water sector, and is intended as a primer rather than a comprehensive handbook. It is nonetheless sufficiently comprehensive to permit design calculations for most water and wastewater treatment unit processes. Core disciplines covered include: • manipulation of equations, including logarithmic and exponential expressions • fluid physics for describing flow through pipes, channels and filters • chemical concentrations and chemical/biochemical reactions • chemical/biochemical reaction kinetics • mass balance for determining fate of materials through unit processes • mass transfer for determining transfer of materials across boundaries within processes • reactor theory for designing biochemical and chemical reaction vessels • cost analysis, including capital and operating expenditure with discounting. New to the third edition: • new chapter on cost analysis • further explanation of the classical unit operations types • illustrations expanded to include unit operation schematics and symbols • new examples and exercises • updated design problem. Watermaths … just add water.

Book Description
Can first love turn into the real deal? Anything can happen in a sizzling new Fool's Gold story from New York Times bestselling author Susan Mallery. Isabel Beebe thinks she's cursed in the romance department. Her teenage crush, Ford Hendrix, ignored all her letters. Her husband left her for another…man. So Isabel has come home to dust off her passion for fashion and run the family bridal shop until her parents are ready to sell it. Then she'll pursue her real dreams. At least, that's the plan, until sexy, charming Ford returns and leaves her feeling fourteen all over again….. Seeing Isabel all grown-up hits bodyguard trainer Ford like a sucker punch. Back when heartbreak made him join the military, her sweet letters kept him sane. Now he can't take his eyes—or his lips—off her. The man who gave up on love has a reason to stay in Fool's Gold forever—if three little words can convince Isabel to do the same.

Book Description
The book serves as a first introduction to computer programming of scientific applications, using the high-level Python language. The exposition is example and problem-oriented, where the applications are taken from mathematics, numerical calculus, statistics, physics, biology and finance. The book teaches "Matlab-style" and procedural programming as well as object-oriented programming. High school mathematics is a required background and it is advantageous to study classical and numerical one-variable calculus in parallel with reading this book. Besides learning how to program computers, the reader will also learn how to solve mathematical problems, arising in various branches of science and engineering, with the aid of numerical methods and programming. By blending programming, mathematics and scientific applications, the book lays a solid foundation for practicing computational science. From the reviews: Langtangen ... does an excellent job of introducing programming as a set of skills in problem solving. He guides the reader into thinking properly about producing program logic and data structures for modeling real-world problems using objects and functions and embracing the object-oriented paradigm. ... Summing Up: Highly recommended. F. H. Wild III, Choice, Vol. 47 (8), April 2010 Those of us who have learned scientific programming in Python ‘on the streets’ could be a little jealous of students who have the opportunity to take a course out of Langtangen’s Primer.” John D. Cook, The Mathematical Association of America, September 2011 This book goes through Python in particular, and programming in general, via tasks that scientists will likely perform. It contains valuable information for students new to scientific computing and would be the perfect bridge between an introduction to programming and an advanced course on numerical methods or computational science. Alex Small, IEEE, CiSE Vol. 14 (2), March /April 2012 “This fourth edition is a wonderful, inclusive textbook that covers pretty much everything one needs to know to go from zero to fairly sophisticated scientific programming in Python...” Joan Horvath, Computing Reviews, March 2015
