Abstract: Process industries need to move
fluid over long distances in pipes of various
capacities, consuming a lot of energy and
raising the cost of establishing and maintaining
pumping stations. Therefore, additives were
used to reduce such costs and overcome fluid
resistance. This work used Poly Acrylic acid
(PAA) added to the water at different
concentrations of 100, 200, 300, 400, and 500
ppm. This work used rough pipes (P.V.C.
covered in sand) of different diameters, i.e., 17,
23, and 26.5 mm, to experiment. After that, the
500 ppm of (PAA+ water) solution was mixed
with 0.3% and 0.6% Zinc Oxide Nanoparticles
(ZnO) at different flow rates, i.e., 44.2, 40, 35.9,
31, 26.2, and 20.8) l/min at 25 °C The effect of
polymer, nanoparticle concentrations, flow
rate, and diameter on percentage drag
reduction (%Dr) and friction factor was
investigated. The results showed an increase of
percentage drag reduction % Dr was observed
as NP concentration and bulk velocity
increased. The drag reduction enhancement
was 47% at 0.6% ZnO NP concentration with
500 ppm of PAA solution at a 44.2 l/min flow
rate and a diameter of 17mm. The experimental
data were also used to calculate the friction
factors.The results showed a decrease in
friction factors when using a 500 PAA solution:
37% and 54% for 0.6% ZnO NP with the
solution.
