Abstract EN
The density important characteristic for being involved in a lot of theoretical analysis of hydraulic systems or lubrication systems.
Many research study examined density at atmospheric pressure, for ease of measured practically or theoretically and at different temperatures, and there is research theory addressed change density when pressure is high, but certified the temperature and other research dealt with and theoretically calculate density at pressures and high temperatures.
Density change and effectively with pressure and temperature, how will be found in practice? In this research will be done indirectly through the conclusion (Bulk modulus) values under different conditions of pressure and temperature and density will be calculated.
Been inferred Bulk modulus practically by measuring volumetric change of mineral oil because of compressibility and at a wide range of pressure and temperatures, this procedure was designed and installed the hydraulic system for this purpose.
Was reached rules the general behavior of the density mass is that when a certain pressure, the temperature increase in equal proportions leads to reduced density equal proportions almost too and theoretical results (which impose a proven Bulk modulus) and the practical results of the density of mass be nearly identical at temperatures medium (fference increases with increasing temperature.
And the effect of heat greater than the effect of pressure on the mass density, as well as there are points where mutual influence equal reverse of heat and pressure, producing equal values of the mass density.
Empirical equation was developed to calculate the mass density derived from the practical results of giving real values more accurate than the previously established equations.
