Abstract
An experiment was conducted on “Development and performance evaluation of an improvised water pumping device for urban applications” at Department of soil and water engineering, SVCEAT & RS, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G). The aim of the work is to efficiently utilize the human energy for lifting and moving the water through the improvised pedal operated water pumping system. Water plays a very significant role in both livestock and agriculture farm. Water use enables plants to be grown and livestock to be raised, which is the primary component of our diet. Traditionally there are different types of manually or animal operated pumps available for lifting and carrying water, some of which are superior to others for various purposes. There are also a lot of scopes to improve the standard and conventional pumping system before searching for new water-lifting mechanisms.
The performance of an improvised gym cycle as a water pumping system was analyzed. This was very useful for exercising an urban area and lifting harvested water to irrigate their field. The performance of this improvised water pumping system was evaluated at the different suction head, different delivery head and at different horizontal distance. The results show that the variation in discharge with different delivery head and different horizontal pipe distance was more significantly affected as compared to the variation in the suction head. It gave the discharge of 0.58 lps (35 lpm) at 3.58 m of suction head, 0.27 m of delivery head and 10m horizontal distance which was enough to provide water for small field, open gymnasium, hostels etc..
Ergonomics is the scientific branch that looks at about the working environment of people. Its objectives to deal with the effectiveness, productivity and overall performance of human during works, also maintain the environment and workspaces to decrease the danger of harm or injury. A different physiological parameter of the male operator on using pedal-operated cycle pump is measured and is necessary to assess the energy expenditure of human during operating water pumping device. How long they can continuously work without getting fatigued. A Subject (human) with BMI 22.2 was found under the with-out load and load condition, minimum change in heart rate (52 and 56 beats/min), oxygen consumption rate (0.59 and 0.63 1/min), energy expenditure rate (8.2 and 8.9 kJ/min) and maximum fatigue time (27 and 16 min.) under load and without pump load conditions respectively. Based on the EER operation system was graded as “light” work.
Improvised water pumping device was tested under different BMI of operator for effective operation, BMI 22.2 was found best for operating the improvised device.
