I'm attempting to calculate the amount of power (in KWH) produced by a water turbine based on x litres of water falling x metres vertically through a tube of x cm diameter(adsbygoogle = window.adsbygoogle || []).push({});

So far i've managed the following:

H = height (distance fallen) (m)

Time = Secs

R = Radius of the pipe (m)

Velocity (m/s) = (2 x H x G) ^ 0.5

Volume / Sec = Velocity x Time x Pi x R^2

mass (kg) / Sec = (Volume / sec) x 1000

Energy = (Mass x Velocity^2)/2 = wattage generated

My questions is.... how do i convert this wattage generated in KWH generated?

Once I have this am i correct in thinking I can do:

(KWH generated / 3600) * (time taken for x litres of water to fall through the pipe).

To calculate the KWH generated by the x litres of water falling?

Any help / guidance anyone could give me would be greatly appreciated. - As you can (maybe) tell i'm by no means a physics graduate but i do have a basic understanding.

Any help anyone could give me would be greatly appreciated.

Many Thanks

P.s For the purposes of this i'm happy to work with a turbine having 100% efficiency.
