| dc.description.abstract | Sling Pump represent the pump by construct the trapeze which its surface is given by the pipe circumference or
certain period. One of the form of exploiting of energy of river stream that is to turn around the propeler of at sling
pump so that sling pump will rotate and irrigate to enter later;then empty into in circumference pipe. Functioning to
conduct the water go to the place which higher elevate so that can be exploited by as irrigation. Many research in
development of sling pump to get the best result ability. Circumference very influencing of work ability the sling
pump. At this research, conducted by development of sling pump trapeze with the big diameter 47cm, small diameter
14cm, length 67cm. Height delivery 1 metre and rotation arranged at 21 rpm by manual that is searching
appropriate current speed. Sling Pump use the circumference of copper pipe and add the amount inlet. Lighter
copper pipe compared to by after plastic so that rotation will be more quickly. Addition sum up the inlet will add the
in put and improve the pressure so that will be obtained by a debit which is more. After done by a examination and
analyse the data, known by that amount inlet influence the yielded water debit, pressure, head losses, energy irrigate
and also efficiency. Optimum debit yielded by that is at the time of amount of circumference inlet 2. Sum up the inlet
2 also yield the biggest debit. Sum up the inlet 2 yielding best ability. efficiency of highest hydraulic Sling pump
efficiency and happened at amount inlet 2. Sling Pump with the circumference of copper pipe yield the better
efficiency from at sling pump using circumference after plastic | |
