The problems below are arranged by chapters. Most of them have quantitative answers. A few of them are descriptive. They are selected to be representative of interesting and significant problem types; many of them can be rearranged or broadened in scope to provide a wider range of problem-solving experience. In many of the chapters the last problem is comprehensive and requires the use of a computer program such as Engineering Equation Solver (EES). In all problems time is assumed to be solar time unless otherwise stated.
Chapter problems that are identified with a leading letter S require running or constructing some part or all parts of a solar simulation program. These problems can be solved using a high-level programming language such as BASIC, FORTRAN, Pascal, etc. Spreadsheets such as Excel can sometimes be used. However, EES is recommended and is available to academic institutions at a reasonable cost from F-Chart Software, LLC (see fchart.com) or for free from McGraw-Hill if certain textbooks are adopted for use in other courses—see http://www.mhhe.com/engcs/mech/ees/na.html. The EES solar functions library (SETP.LIB) is used whenever convenient. This EES library can be downloaded for free from fchart.com under EES “Additional Items.” The S problems associated with the Introduction use the free simulation program CombiSys and are used to illustrate solar system behavior prior to the detailed study of subsequent chapters.
