Fluid System Turbines and Pumps

The video tutorial covers the concepts of pump and turbine power, explaining how they are calculated using specific weight, flow rate, and head. It discusses the efficiency of pumps and turbines, providing examples to illustrate these concepts. The tutorial also includes a practical example of a hydroelectric plant, demonstrating how to calculate power output and efficiency in real-world scenarios.

What is the primary purpose of a turbine in a fluid system?
