Material Properties Material properties of gases, fluids and solids - densities, specific heats, viscosities and more.Involving velocity, pressure, density and temperature as functions of space and time. Fluid Mechanics The study of fluids - liquids and gases.Densities Densities of solids, liquids and gases.Boiling Points Boiling points of elements, products and chemical species at varying conditions. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. It also shows the saturation pressure with changes in temperature.Īt the critical point there is no change of state when pressure is increased or if heat is added. The curve between the critical point and the triple point shows the pentane boiling point with changes in pressure. The phase diagram for pentane shows the phase behavior with changes in temperature and pressure. However, if heated above 36☌/97☏ it becomes a gas, and when cooled it becomes a solid. Pentane is a liquid at standard conditions.

Property The phase diagram of pentane is shown below the table.Ĭhemical, physical and thermal properties of pentane : Both the liquid an the vapor are flammable. The boling point 36☌/97☏, and the vapors are heavier than air. It is a component of some fuels and is employed as a specialty solvent in the laboratory. It belongs to the organic class alkanes, and is naturally present in crude oils and condensates. The graphic curve will be updated as well.Pentane, C 5H 12, is a clear colorless liquid with a petroleum-like odor. All other values will be re-calculated automatically. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. The use of any of the calculators’ results is at the user’s sole risk. The calculator below is for informative purposes only. You can calculate pre-filled values of oil classified by ISO 3448 with grades VG22, VG32, VG46 or VG68 (at viscosity Index = 100) or enter specific values for any other oils. These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. the Viscosity Index (VI) by the formulas specified in ASTM D2270 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ISO 2909 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ГОСТ 25371-2018 (`Нефтепродукты.the kinematic viscosity values, depends from temperature, calculated by the formulas specified in ASTM D341 – (‘Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products’).The interpolation calculator provided below is used to determine:
