This document provides an introduction to the Francis turbine, a type of water turbine. It discusses velocity triangles, which illustrate the velocity components of water flowing through the turbine. It also mentions that the turbine is designed to have zero whirl, or rotational velocity, at the outlet. The document was prepared by an assistant professor as part of a fluid mechanics and machinery course at Panimalar Institute of Technology.
