thanks pal. I got enough information

thanks pal. I got enough information ;)

of course i did . I'm hope someone can give me some references so i know where i should refer when i want to design a turbine for such set up. It is really tough because i have no idea so far.

well, the truth is that we are actually focusing on efficiency, and not trying to harness additional power. It is believed that this vortex powerplant enable us to harness more power than the usual hydro powerplant. Am I wrong? As for my part, i was asked to design a blade to increase...

Assume that it is a free vortex, can i assume that V(entrance) = V(angular) ? I am also planning to use Bernoulli equation where Q1 = Q2 . That means inflow = outflow. However, The water will rise to a certain level before it became steady. Apply Bernoulli at the Point Inflow And Point Outflow...

Look at this two examples, and let me know if you're able to help me out @_@

Let's assume you have a cyclinder tank. You drill a hole at the bottom, middle of the tank. The water will drain out and have the effect of a vortex. Just like A Sink. I need the calculations for such vortex, and i also need to know how do i harness the maximum torque from such vortex.

Anyone has ever came across this powerplant? I'm a final year mechanical student, and i was asked to design the turbine blade to harness tp obtain the maximum efficiency of the hydro vortex. I'll be glad if someone can help me out by giving me some vortex calculations,simulations or any related...

i thought this is like a momentum question, but i dun get it , why there's no mass given -_-

d = 15t + 1/2(-0.5)t^2 <<--- for the bus d = 6t + 1/2(2.5)t^2 <<-- for the sport car. Solve the simultaneous equation and you had it. I hope I'm right @_@. My answer is 6seconds.
