1. Fluid Mechanics for Power Generation P M V Subbarao Associate Professor Mechanical Engineering Department IIT Delhi An Essential Science for All Thermal Processes !!!!!

4. Truths of Modern Life Using the steam/Gas to make the Electric Power ! Rotating the shaft(Rotor) is the ultimate goal of any power plant !!! How do you get mechanical power from Live-steam or Gas? “ How to get super energized (Live) steam/Gas ? “ How do u generate life in live-steam ? A science of Fluid Power is basis for all current and future power generation technologies. This Science of Fluid Power is called Fluid Mechanics.
