商品簡介
The 430 worked problems in this study guide are divided into four sections corresponding to each grade level for water distribution. Each section walks through the solution of progressively more difficult conversion problems, average and percent calculations, pressure problems, volume determinations, flushing time problems, dosage calculations, and pumping discharge problems. Appendices list conversion factors, formulas, chemistry tables, and maximum contaminant levels. Annotation c2007 Book News, Inc., Portland, OR (booknews.com)
