Manual automation of the borehole using a pendulum
This research is about the development of a borehole which operates in such a way that the pumping action is initiated by the swinging of the pendulum. The human arm, leg are used to operate the borehole by swinging the pendulum. Therefore less amount of energy is required to produce a reasonable output. According to the study, three machine parameters determine the amount of discharge obtained from the borehole and these parameters are length, mass and position of the pendulum. Generally, i found out that when the length of the pendulum is increased, the discharge obtained in a given time also increases and a graph of discharge against length is a curve which appears in an increasing manner. Further, when more weights are added to the pendulum, the discharge obtained in a given time increases and a graph of discharge against mass is a straight line with a positive gradient. Concerning the position of the pendulum, the more the angle the pendulum is displaced, the more the input energy and this inturn results into an increase in discharge obtained, the graph of discharge against input energy is a curve which appears in an increasing manner but less steep as compared to the graph of discharge against length obtained in the former case. A long meter rule was used to measure different length of the pendulum, known masses each of half kilogram were gradually added to the pendulum, a protractor was used to measure the angle of displacement of the pendulum, a stop clock was used to determine the time at which readings were taken and a 100 ml measuring cylinder was used to determine the discharge obtained at all the three parameters. However due to the fact that most materials that i used in the project were wooden and other plastic, further research need to be done when metallic materials which are more efficient are used so that even more weights can be added to the pendulum without breaking and hence large output of the liquid is obtained.
