Length of Drive Pipe To Hid Ram Pump Characteristic

Abstract

Hid ram pumps is a very specific device to lift water. The uniquess of this device is indicated by the hid ram energy‘s used to lift is energy of water that will pumped. Therefore, hid ram pumps is very environmentally friendly and save energy. Water energy used of hid ram pumps is potential energy of water from a elevation drove through drive pipe. This paper aim to understanding hid ram pumps characteristic as lifting the water as drive pipe variation length. In the research, the observation did with four drive pipe variation length, namely 1,0 m, 1,5 m, 2,0 m, and 2,5m. High water fall and drive pipe diameter is 1,5 m and 2 inch, respectively. This device is executed in Civil Engineering Laboratory of Muhammadiyah University of Surakarta. Variables that appear is described in the gRAPh of the relationship between the variables. The result indicate that the longer of drive pipe will generate the pump debit (Q) that bigger and flow ratio (Q/(Q+QL)) is bigger, too. Increasing ratio of high falls by delivery high (h/H) indicate that decreasing of the pumps effectiveness and flow ratio is increase of drive pipe length variations.
