Abstract: The nomograph developed by Frost is widely used to estimate sprinkler evaporation losses. The original data from over 700 tests used to develop the nomograph are apparently lost. An equation is developed to approximate the ...

Abstract: Partial irrigation is supplying less water than a crop needs for full production. Partially irrigating crops is intended to stretch water supplies and increase total crop production and profit. Pakistan is short of water ...

Abstract: As NASA progresses toward the construction and assembly of the international space station, the dynamic influence of massive, highly flexible payloads becomes more and more of an important consideration. In particular, ...

Abstract: The complex eigenvalues of frequency are computed for Hough functions of negative equivalent depth, using the method of Longuet-Higgins. The positive kinetic wave energy and negative wave potential energy of unstable modes ...

Abstract: A digital display of the location and intensity of the most intense radar echo in a selected sector is provided by a digital comparator with shift register storage of digital video signals from the National Severe Storms ...

Abstract: A new growth equation for pure water and solution droplets with radii?1µm has been developed which features discrete vapor and temperature fields at the surface of growing droplets. The discrete fields are created by the ...

Abstract: Four two‐stage pipe expansions were designed, constructed, and tested to estimate their annual operating cost in irrigation service. The hydraulic performances of these fittings were compared with past two‐stage expansion ...

Abstract: A simple numerical model is used to demonstrate that momentum exchange between wave and mean flow can substantially modify the process of ?breaking? of internal gravity waves at great height. The momentum exchange results ...

Abstract: The Canadian super critical water-cooled reactor (SCWR) concept requires materials to operate at higher temperatures than current generation III water-cooled reactors. Materials performance after radiation damage is an ...
