The range of topics covered in this book has been extended significantly when compared to rather limit material usually presented on the Reynolds transport theorem (RTT) in textbooks or monographs. The material is packed into three major parts: (a) devoted to homogeneous systems, includes derivation of the RTT of the material and control volume (CV) formulations concluded by the RTT equations expressed in terms of the moving CV; (b) assigned to two-phase systems, incorporates fundamental cases namely, with storage in phases only, and with combined storage both in phases and interface split...
