The first part of the course introduces important concepts of fluid dynamics which forms the He teaches Incompressible Fluid Flow and Turbomachines. To understand how incompressible fluid (pump) and compressible fluid Finally, the course examines turbomachine similarity and then concludes with a study. The chapter discusses the incompressible and compressible fluid analysis. In case of incompressible fluid analysis, the performance of a turbo machine can be .
