Hi, > HI Any body can tell me how i can determined any micro hydro plant > capacity if i know his Discharge,water head.
Very simple: Every kilogram of water is attracted by Mother Earth with a force of 9.8 Newton. Force times distance traveled gives energy. So, one liter of water falling one meter gives 9.8 Joule of energy. If this happens every second, you have a continous gross power of 9.8 Watt. Then you must subtract the losses of the whole system (penstock, turbine, transmission, generator) to reach the final electrical power output. > If any formula please tell me in brief. Electrical power (Watts) = 9.8 * flow (liters per second) * head (meters) * efficiency The efficiency should be between 0.3 and 0.8, depending on the quality of the system. An example can make things simpler: Suppose you have a stream giving 30 liters per second, with a usable head of 25 meters, and a system efficiency of 50%, or 0.5. You will get: 9.8 * 30 l/s * 25 m * 0.5 = 3675 Watt. Clear? Best regards, Manfred. P.S.: This is my first post to this group. I hope to buy a piece of land soon, build my definitive home on it, and power it from a microhydro setup. So I joined here a few months ago, to get into gear! -------------------------- Visit my hobby homepage! http://ludens.cl -------------------------- ------------------------ Yahoo!
