Abstract
This experimental study presents fluid flow characteristics obtained for a
non-ferrous metallic water nanofluid, copper-water mixture, through a
one-horsepower centrifugal pump. The results obtained for three
different pressures rise of 3.8, 4.2, 4.8 (bar) by pumping copper-water
nanofluid through a constructed pump test unit, with the addition of 5g
of copper nanoparticles to 20L of water are Head (m); 0.17, 0.33, 0.41;
Flow Rate (m3/s); 0.463070155, 0.285632676, 0.076961558; Brake Power
(Kw); 0.0723825, 0.1050225, 0.041503 and Efficiency; 0.6899997,
0.6399991,0.5999997, while for 10g of copper in 20L of water are Head
(m); 0.15, 0.28, 0.37; Flow Rate (m3/s); 0.4606172, 0.2175568, 0.0949577;
Brake Power (Kw); 0.0814823, 0.0914652, 0.0591155 and Efficiency;
0.6099998, 0.5699993, 0.5199997. The pump flow rate was observed to
decrease as a higher head is attained while the head gained increases
with an increase in pumping pressure. The head attained due to
pumping was observed to reduce as the copper nanofluid concentration
increases, while the pump vibration increases as the particle
concentration increases. There was an observed temperature rise in the
components of the nanofluid pump testing machine due to a rising
temperature of the copper nanofluid during the pumping operations.
Lastly, this experimental research clearly shows the impact of copper
nanofluid on the pumping power, flow rate, head gained, pump speed,
and pump efficiency.
