Abstract. The thermophysical properties were estimated experimentally at veracious weight loadings, and temperatures of ZnO+Fe3O4/water hybrid nanofluids. Later the experimental data has been used for artificial neural network (ANN) to train the algorithm. In this study, the temperatures range, and weight concentration range used are varies from 20 oC to 80 oC, and 0% to 0.5%. Levenberg- Marquardt model was considered to train the ANN algorithm. Experimental outcome shows thermal conductivity is enhanced by 4.153%, and 8.689%, moreover, the viscosity is enhanced by 48.762%, and 15.806% at 0.5 wt%, and at 20 oC, and 80 oC, over the base fluid. The density is enhanced by 4.687%, and specific heat is decreased by 1.052% at 0.5 wt%, and at 20 oC, over base liquid. The ANN result shows that, for the trained data, the mean square error for thermal conductivity is 6.7951e-7, for viscosity is 0.00001, for density is 1.9428, and for specific heat is 2.7528 with a correlation coefficient of 0.9997, 0.9998, 0.9960, and 0.9944. Finally, from the ANN, the polynomial regression equation has been developed.
