Session 19 Testing installed wind system

TOTAL TIME: 2 Hours

OBJECTIVES: To set up test conditions to allow testing of what has been built.

To gather DATA on the performance of the system which has been built.

MATERIALS: Two 5-gallon drums (kerosene cans), watch, and anemometer Water supply (pond, well, river, tank or 55-gallon oil drum)

PROCEDURES:

Step 1: 15 minutes

Assemble the test apparatus, which consists of a hose or pipe that can reach from the outlet of the pump system to a container of known volume. Then monitor the amount of water pumped in a given amount of time by a certain wind speed.

Step 2: 1 hour

When the test apparatus is set up, allow the pump to fill the container at a specified time. Record the amount pumped in a minute and the windspeed every 10 seconds during that minute. If possible, change stroke length and repeat the test to optimize pumping rate.

Trainer Note

For the data collection, accurate recording of windspeed, height pumped, amount pumped, and time pumped are required. In addition, the exact capacity of the cans used must be known. Make a number of runs at various speeds. Then make a graph of windspeed versus foot-gallons per minute (or meter-liters per minute).

Step 3: 45 minutes

Calculate and graph or chart results.
