Question

The formula given by pak & cho's to find the density of nanofluids () is

Answer 1

Explanation:

Density measurements were performed on three different nanofluids containing aluminum oxide (Al2O3), antimony-tin oxide (Sb2O5:SnO2), and zinc oxide (ZnO) nanoparticles in a base fluid of 60:40 ethylene glycol/water by mass. First, a benchmark test for the density of the base fluid is presented showing excellent agreement with the data presented in the handbook of the American Society of Heating, Refrigerating, and Air Conditioning Engineers. Next, density measurements of the above-mentioned nanofluids over a temperature range of 0C to 50C for several particle volume concentrations are presented.
