This study aims at the calculation of pressure drop from simulation of internal nanofluid flow in a new and long stainless pipe (1.4 m long and 0.01 m diameter). Calculations were made from numeric simulations which were based on theoretical models and experimental proprieties of three nanofluids: graphene nanodiscs with water, titanium oxide nanospheres with water and iron oxide nanospheres with water. Different concentrations were considered in each kind of nanofluid. Calculus of pressure drop were based on Darcy-Weisbach equations model. It was considered a fully developed turbulent flow for two numbers of Reynolds (Re), 4583 and18187. After analysis, it was verified a decrease in pressure drop values for each nanofluid, in parallel with the decrease of particulate quantities.
