This book does a good job of covering all of the relevant concepts of heat transfer. I would give this 4 or 5 star rating, however the author makes mistakes in solving his own practice problems, but whats worse is the author can not even use values from his own tables correctly (for example in problem 4.3 the author uses a cp=473, when clearly in the table it is stated as cp=0.473). Errors like this are unacceptable, especially when many problems reference other problem. I have tried to reach the publisher to help correct these errors, but they have yet to get back to me.
