Influence of temperature and pressure on the density and speed of sound of N-ethyl-2-hydroxyethylammonium propionate ionic liquid

Theoretical Analysis of a Hydraulic Drive System. The Influence of the Work Environment on the Performance of the System

“…The study of real fluid flow is generally difficult to address by complete theoretical methods, due to the special complications caused by a number of disturbing factors such as fluid friction (viscosity), turbulence, driving solid particles, presence of internal heat sources etc. The knowledge of fundamental properties behavior in a system can help us understand the nature of molecular interactions and so we can determine other thermodynamic properties [4], [5], [16], [17]. Temperature and density are factors that affect the treated metals, which have an important influence on the macroscopic mechanical properties and the stability of materials [6], [7].…”
