| dc.description.abstract | ZULFAHRI YUDHA DUANA : Effect of Variation of Measurement of Air Tube
on Hidram Pump’s Performance, Supervised by SUMONO and RISWANTI
SIGALINGGING.
Hidram Pump is one kind of pump that needed no electrical energy as it
exploits air pressure and the water pressure as it’s power booster, so Hidram
pump is one of water pump that isn’t using fuel and relatively cheap. This reseach
measured rate of flow, coefficient and efficiency of pump. The aim of this reseach
was to know the influence of variation of measurement of air tube with the same
volume (2494,64 cm)3
, the high that the was 54,67, 19,68 and 10,04 inches, and
the diameter was 3, 5, and 7 inches on water rate of flow resulted.
From the trial and calculation results the variation air pump measurement
with the same volume but with different diameter and high that no significant
effort the pump performance. The rate of flow input was 1,176 1/s. The output for
3 inch tube was 0,330 1/s, for the 5 inch diameter was 0,336 1/s, and 7 inch
diameter was 0,338 1/s. The coefficient of rate of flow obtained was 0,497 for the
tube diameter 3 inch, 0,504 for the diameter 5 inch, and 0,498 for the diameter 7
inch. The highest efficiency for found in air tube by the meter of 7 inch as big as
28,74% and the value of efficiency dispute was just 0,17% | en_US |
