Rainfall Driven Micro Hydro-Generating System

In summary, The goal is to design a Rainfall Driven Micro Hydro-Generating System that produces 30 W at 12 V regulated DC. The equation for power generated is equal to Head x flow x g x efficiency of the turbine. The length of the water pipe may affect the power generated as it could result in loss or gain of momentum, depending on the orientation. To measure the flow, rainfall is used.

Homework Statement


Im trying 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.
Is there any relation between the length of the water pipe, the speed of rotation of the turbine and the generated voltage?
and how to measure the flow? (Im using rainfall here)

Homework Equations


the Power generated is equal to Head x flow x g x efficiency of the turbine


The Attempt at a Solution


I'm using a pelton turbine, I found how the power generated is calculated

Not entirely sure what this thing is meant to look like, but I presume the length would matter as that's a distance, so with a greater distance you may lose power as it takes time for water to travel a longer distance, possible loss of momentum.

Alternatively, a longer pipe might mean increased momentum if it was vertically pointed, or on some kind of incline; depends on orientation.

1. What is a rainfall driven micro hydro-generating system?

A rainfall driven micro hydro-generating system is a type of renewable energy system that harnesses the power of flowing water to generate electricity. It uses a small turbine to convert the energy from the flowing water into electrical energy, which can then be used to power homes, businesses, or other devices.

2. How does a rainfall driven micro hydro-generating system work?

The system works by diverting a portion of the natural flow of a stream or river into a small turbine. The turbine is connected to a generator, which converts the kinetic energy of the flowing water into electrical energy. The electricity can then be stored in batteries or fed directly into a power grid.

3. What are the benefits of using a rainfall driven micro hydro-generating system?

There are many benefits to using this type of system, including its reliability, low maintenance requirements, and environmental friendliness. It also has a low impact on the surrounding ecosystem, as it does not require the construction of large dams or reservoirs.

4. Are there any limitations to a rainfall driven micro hydro-generating system?

One limitation of this system is that it requires a consistent and reliable source of flowing water. If the water source dries up or slows down significantly, the system may not be able to generate enough electricity. Additionally, the initial installation cost can be high, although the system can provide long-term cost savings.

5. Can a rainfall driven micro hydro-generating system be used in all locations?

No, this system is not suitable for all locations. It requires a significant amount of flowing water, so it is best suited for areas with high rainfall or near a large body of water. It also requires a certain amount of elevation drop, so it may not be suitable for flat or low-lying areas.
