Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Basically I need help working out how much energy we can potentially produce.

We have a waterfall 50m high that has a constant year round flow. We would take off water into a 6" vertical steel pipe at the top and run it to the bottom into a turbine. I don't know the friction of the pipe but can I work this out? Solutions that find the kinetic energy of the water at the bottom is fine as I dont know the conversion rate of a typical micro-hydro turbine either.

I do know that:

If that helps. Thanks in advance. If you need any more data I'll try find it.Code (Text):

P[SUB]max[/SUB] = Q[SUB]max[/SUB]*H[SUB]max[/SUB]*e[SUB]max[/SUB][SIZE="5"] / K[/SIZE]

Where:

P[SUB]max[/SUB]=Maximum Power Available (kW)

Q[SUB]max[/SUB]=Flow (Volume/time)

H[SUB]max[/SUB]=Head (Vertical drop in m)

e[SUB]max[/SUB]=Efficiency of the turbine (use a value of 1 for max power available)

K=Unit conversion factor (see table below for some common values)

For Q measured in K is equal to

ft3/min 708 (ft4)/(min*kW)

ft3/sec 11.8 (ft4)/(sec*kW)

l/sec 102 (l*ft)/(sec*kW)

gal/min 5302 (gal*ft)/(min*kW)
