In transportation of fluid, the drag reducers in pipeline are important parameters because of drag reduction increased the ability of pump fluid when adding small amounts of additive to fluid. The frictional pressure loss in pipes is waste energy and it very costly so the drag reducing minimizes flow turbulence, reduces the costs of energy and increases throughput. The transportation of reducing crude oil is very difficult and needs some treatment to improve its transportation and this is because of its high viscosity. The purpose of this research is to study the effect of nanoparticles of copper oxide on viscosity of R.C. and other parameters when transport it through pipes. This research investigated the viscosity, pressure drop and other parameters in three pipes (0.0127, 0.01905 and 0.0254 m) I.D. with different concentrations (0.00625, 0.0125, 0.01875, 0.025 and 0.0375 (gm/L) w/v) at 50 oC and the flow rate is 50% of maximum. The results show that the performance of the drag reduction is much better in the larger pipes diameter than the smaller one. Also, the CuO NP's effect on R.C. viscosity and the maximum viscosity deviation is about 4%. In Addition to CuO NP's to R.C. has reduced the %Dr, pressure drop and shear stress.
An assessment was made for the impact resulted by the addition of (DO) and (DOA) on the octane number and Reid vapor pressure (RVP) of gasoline with different chemical compositions. The locally produced gasoline had been blended with three different ratios (v/v) of the additives, i.e. 8, 10 and 15%. The octane rating of gasoline was observed to continuous increased and linearly with the addition of (DO and DOA). The DOA-gasoline blends produced higher octane number. The two additives observed that decreased significantly the RVP and CV of the original fractions when blended with gasoline. However, additives were add in (8, 10, 15%vol) to gasoline blend, increasing RON was (0.9-23.9).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
