Dear Joe O,

houston2000 <houston2000@peoplepc.com>

For a given hydropower installation, height and cross section of the penstock pipe are fixed. In running water condition the rate of discharged water and its velocity are constant.

1. Velocity is achieved by height difference between the intake and discharge points, higher the difference the greater is the velocity of running water. K.E.?  So v is other side of p difference. V determines the RPM of the turbine.

 2. In a running uniform water column, the pressure effect at any point between inlet and outlet points are same (the pressure effect is uniform throughout the water column. This is not so in standing still water column where pressure varies according the height or depth). - Fluid properties.

3. So each turbine will have the same total force due to the height of the water column independently. Whether one or more turbines are installed, it makes no difference. Nowadays turbines are made very efficient, almost 98%.

4. The force of gravity is acting here, the G is constant, never reduced, never shifted and never blocked at a given point; so the total force available at any given point of the running water column is constant and independent to each other.

5. If it were zero pressure difference after the first turbine water will stop but you know water continues with the same velocity. Velocity of water before and after any turbine is the same. Turbines don’t decrease the power of running water. So you can run uniformly as many turbines as space allows between the intake and discharge points of water column.


(# I made presentation on this topic at many places like hydropower association, professors, engineer’s association, public places etc. Comments like yours always came from the engineers only. I wonder if you are an engineer! I earnestly request you to go through the explanations in my blog: devbahadurdongol.blogspot.com)

I am proud of you for your interest on this matter.

With regards,

Dev

Dear Joe O,

"that the TOTAL OUTPUT was reduced with each additional turbine added....his experiment and hypothesis is absurd"

Since the water will continue with the same velocity after hitting the runner of the turbine as before hitting the runner, how can you claim the total out put is reduced by each additional turbine?, if that is so then the velocity of water will also be decreased.
