This project is about development of a solar water heater with increased thermal efficiency using nanofluids as
enhancement medium compared to conventional solar water heater which uses water as the working medium to overcome the
inadequate heating of water in the seasons like rainy and winter. In this project Al₂O₃-H2O nanofluid is used as working
medium, where Al₂O₃ is used as nanoparticle and water is used as base fluid.
