Objective/Motivation
•Hydroelectric Power is very clean on small scales
•Pacific NW: Lots of water
Measure the flow of the stream to estimate the available hydroelectric power

Stream Flow Measurements
•Materials:▫Stopwatch▫Current Meters▫Measuring Tape▫Boots

Procedure1. Determine evaluation sites
• Tried 3 points along the stream, decided on one
2. Take Recordings▫ Width (m)▫ Depth (m)▫ Flow Rate (m/s)▫ Water Head (m)
3. Analyze Data▫ Volumetric Flow (m3/s)▫ Determine Kinetic Energy▫ Determine Gravitational Potential Energy

Power Generation and Cost
•Run-of-the-River: Pico hydro<500 W, <2000$
•Penstock: ~1000 W, ~10,000$

Parallel Axis• Commonly used on
large scales• Efficient: up to 90%
(on large scales)• Expensive, hard to
fabricate, especially on small scales
