Total Power generated

Hello,

This is sudhanva madhukar mahamuni. I am not expertise into power generation but i can tell you one thing that it is difficult to generate high rating power at such a small velocity. But if quantity of water is much higher then you can go for the same.

Regards

Mahamuni

If a river has no head, it has no kinetic energy.

Hello, sorry i missed to mention few more details.

Actually in reality River does have head and it flows with kinetic energy. The reason why i've said theres no head is because i'm not intending to build up reservior, penstock, etc. Also, i only need to generate upto 10kW of energy. The suitable turbine i came up with is crossflow... any idea if i'm approaching in right direction? Thanks

Ever heard about bulb turbines?

Did you search the net? The above results are from when I checked bulb turbine and then as low head hydro turbine. This is what we used to do in the library (then forget Google, even PCs were not there).

This is called the survey and study of existing literature.

I've checked all the reaction turbines but they are all only suitable for higher demands of electricity. I've to generate just about 10kW.

I've one more question.... From bernuollis equation i discovered the equation

Pressure(P) + (Density(Rho)*velocity(v)^2)/ 2 + Density(Rho)*Gravity(g)*Height(h) = constant (0)

Because theres no head i've got rid of "Density(Rho)*Gravity(g)*Height(h)" and ended up with

Pressure(P) + (Density(Rho)*velocity(v)^2)/ 2 = constant (0)

Can any1 tell me if the above equation is still viable? Thanks

Your tutor is your guide also, kindly clarify your doubts with him/her also. I could not understand the pressure 3.5 kN/m^2 (equivalent to 350 mmwc), where you are measuring. Is it that the hight of stream is 350 mm?

I suggest to costruct slanted obstuctions on both sides of inlet (to make conical inlet), so that water from large cross section has to pass through smaller area of cross section at inlet. This may result in raising the level few mm temperarily and increased inlet velocity which will be helpful in getting more power from water.
