Development and usage of a water lifting device in agriculture Assignment

Development and usage of a water lifting device in agriculture - Assignment Example Several designs were tested before arriving at the present design. Most of the third world countries depend on agriculture to sustain their population and earn revenue through export of their production to other countries. Agriculture requires usage of water either from a river or through ground sources. Ground water being dominantly available requires specialized tools to lift the water to the fields for the purpose of irrigation. The present report focuses on development of a water lifting device that could a eco friendly without compromising on the economic parameters of design. The objective is to achieve a fairly good amount of acceptable proportion in the design of water lifting device with regards to sustainability. Two methodologies have been tested for the same. Use of naturally available sources of energy that can be renewed was made in the design of water lifting device. In areas, where sun light or solar power was in abundance, solar powered devices where used to power up the pumps that lift water. In cases, where animal and organic waste was in abundance, design of power sources that work using organic waste as fuel was utilized. Care was taken in arriving at the best combination of photovoltaic cells. ... Yield output of 50W per module at full strength of sunlight equal to 1000W/m2 Type Biomass energy powered pump Pump type Submerged pump with surface motor Pump specifications Suitable for testing conditions. 1kW capacity considered Biomass Electricity obtained from mini stations operating on organic waste as fuel Capacity of Biomass Depending on the amount of organic waste, capacity is determined. SECTION 3 Description of the Final Design: Two design strategies are tried out with regards to conditions prevailing in the testing areas. Two testing conditions were used. 1. Areas with surplus solar energy: 2. Areas with surplus organic wastes Help was solicited from FAO Corporate repository for arriving at design of the system. Section 3.1: In condition 1, use of photovoltaic cells was adopted, refer Figure 1 below. In both the cases, similar type of motor or pumps was used. Figure 1 An array of photovoltaic cells was used to provide sufficient power to run a motor of a specified capacity (look for specifications in section 2). Care was taken in arriving at the best combination of photovoltaic cells. Since photovoltaics are costly and the amount of investment that goes into purchasing the units defeats the very objective of cost minimization in the short run, photovoltaics developed from locally available sources with good output were utilized. Please refer to section 2 for output specifications. The design resulted in an environmentally friendly output as the source input used now is a natural one compared to earlier ways wherein fossil fuels were used and resulted in pollution. The design is economical as locally available sources of photovoltaics were used with higher output and lower maintenance. The
