Rainfall driven micro hydro system

[cutegaljessy]

Homework Statement

I need to design a Rainfall Driven Micro Hydro-Generating System
Under normal operation, the generating system is expected to produce 30 W at 12 V regulated DC

Homework Equations

1st how to calculate the flow of rainfall
2nd: what are the formulas that I should use?
and what do I need to calculate?

The Attempt at a Solution

I found the formula P = net head x flow x g
I still need the remaining formulas

Welcome to the PF.

This wikipedia article is a good intro to hydroelectric power generation:

http://en.wikipedia.org/wiki/Hydroelectricity

And it has a link out to the article on Micro Hydro generation. These articles would be a good place to start your research for your project.
