Nanoparticles are suspended into methanol base fluid at four different concentrations which are 0.01, 0.05, 0.10 and 0.15 vol% and the nanofluids preparation were completed through sonication using ultrasonic homogenizer. The density of prepared nanofluids was measured by KEM-DA 130N density meter at four different temperatures (5, 10, 15 and 20 °C). The results show that the density increases with increase of volume concentrations while the density decreases with increasing temperature and the increment is observed about 2.2% over the base fluid at 0.15 vol% and 20 °C temperature.Read More
