WHAT IS HYDROMX’S SPECIFIC HEAT? July 7, 2022 By While this is a common engineering question, it is also a misapplied question for nanofluids. Specific heat is measured with the fluid static. HVAC systems operate with the fluid in motion and better yet, the fluid in turbulence. Nanofluids outperform other fluids when in turbulence. Also, some nanofluids (including Hydromx) are non-Newtonian which means their characteristics change under stress. Hydromx is a sheer-thinning nanofluid where its fluid pressure drop improves as it is placed under stress.
