Calculate the Liquid drops of spreading on the Horizontal plate

Small liquid drop which is placed as the horizontal plate, as shown in below sketch. The liquid drops of spreading displace the neighboring gas, to achieve the configuration of equilibrium, by the contact angle  =  Ignore the gravity for small drop, the spreading’s is occurred by simultaneous process. Calculate the thin spreading drops by using the lubrication theory which is calculate as the lubrication parameter. (Davis , 1983)

In the agriculture sector, in Spain water scarcity is partially due to the poor organization of this reserve. In farming the main objective of this study is to represent the main factor that is related to the efficiency of water usage. Southeast Spain that considers the most arid areas of the country it focuses on the Almeria coast, as well as in general, as in this zones the foremost directs of managers use water. In Spanish, many of these farms are between the most water efficient in agriculture but throughout the sector this efficiency is not generalized. In this area water performance is conducted by the comprehensive assessments, by the usage of on farm, structural, socio-economic, as well as environmental information.

Descriptive analysis as well as cluster analysis these are the two statistical methods are used. As a result, we identified the two results; regarding the water usage we identified the farms that are less and the other is more efficient. The common characteristics of both the farms are analyzed within each group as well as several conclusions could be reached the difference among the groups with the analysis of one way ANOVA. In irrigation new technologies as well as innovation are used and the main difference among the center of two clusters.  By more educated farms the most water efficient farms are characterized, a larger degree of invention, technology about new irrigation, as well as also water issues awareness and sustainability of environmental. In similar arid the finding of this study could be extensive to farms along with the areas of semi-arid as well as to appropriate policies contribute to development to enhance the usage of efficiency of water in the sector of agriculture.

In the last five decades this agriculture is the key driver behind the enormous development of socioeconomic development has undergone the province. On the part of the family farms, along with the great effort this becomes the reason for the hugely successful activity of agriculture. 13500 farms are consists for the productions, with the three hectares. Water is extremely significant as it is an irrigated agriculture. As rainfall is very low, so weather condition are extremely favorable.  220 mm is the average annual precipitation, also must used the all the sources of available water. 80% groundwater is the main source, through the desalinated water as well as waste water reused.

One acre will cover the 27154 gallons as in the table we show some soils;
