Windpumps - Appropedia: The sustainability wiki
A windpump is a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land. Once a common fixture on farms in semi-arid areas, windpumps are still used today where electric power is not available or too expensive. The first half of the 20th saw further development, particularly a move toward propeller type wind …

As the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 [49, 50]. The parameter setting of the ball mill is shown in Table 1.

Measurement of Soil Moisture: 4 Methods
Tensiometers measure the matric potential of soil moisture in situ (field) with the use of a porous clay cup attached to a tube filled with water. The water in the cup and tube is attached to a vacuum gauge or a mercury manometer (Fig. 7.10). As the soil dries, water moves out through the porous cup, creating a suction or vacuum on the water ...
