Homework Help: Rainfall driven micro hydro system

  1. Oct 21, 2011 #1
    1. The problem statement, all variables and given/known data
    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

    2. Relevant 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?

    3. 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:


    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.
