SWCNTSs nanofluids have high mechanical strength, good electrical conductivity, and high tensile strength. This research focuses on analyzing the thermophysical properties, heat transfer characteristics, and pressure drop of Single-Wall Carbon Nano Tube (SWCNT). Volume fractions used in nanofluids are 0.1%, 0.3%, and 0.5% and PVP surfactant 0.02% with distilled water as a base fluid (Aquades). SWCNTs nanoparticle characterization process was carried out by means of thermal conductivity test, and specific heat, viscosity test, density test, mettler toledo, FTIR (Fourier Transform Infra Red) test, XRD (X-Ray Diffraction) test, and SEM (Scanning Electron Microscope) test. The results obtained in this study include thermophysical properties, namely for the highest thermal conductivity of 0.690 W/m.oK, density of 1736.95 kg/m3, viscosity of 0.00166 kg/m3, and for specific heat of 3097.08 J/kg.oC, then for the heat transfer characteristics, the result is that it has an increase in the value of the heat transfer coefficient of 4.17 W/m2.°C, and the pressure drop value gets a value of 1.1968 N/m2.
