The following thermodynamic properties are calculated:ĭensity, dynamic viscosity, kinematic viscosity, specific enthalpy, specific entropy, specific isobar heat capacity cp, specific isochor heat capacity cp, thermic conductivity, coefficient of thermal expansion, heat conductance, thermal diffusivity, Prandtl-number, coefficient of compressibility Z, speed of sound.Ĭalculation of Nitrogen : if you found an error, please mail to: No garanty for correctness. Solution: For SAE 30W oil at 20☌ (Table A.3), take 891 kg/m3 and 0.29 kg/m-s. Do you agree A million newtons is a lot, so this sounds like an awfully high flow rate. Lower limit for calculation: -210 C, 0.13 bar bar upper limit: -148 C, 33 bar. The Dynamic Viscosity Of Air (R 0.26 J/Kg K) At 32☌ And 191 KPa Abs Is 1.6510-5 Kg/M S. Chapter 6 Viscous Flow in Ducts P6.1 An engineer claims that flow of SAE 30W oil, at 20☌, through a 5-cm-diameter smooth pipe at 1 million N/h, is laminar. Lower limit for calculation: -200 C, 1 bar upper limit: 1000 C, 1000 barĬalculation of thermodynamic state variables of nitrogen in saturation state, boiling curve (15 pts) Temperature Mass density, P Dynamic (☌) (kg/m) viscosity, (N- s/m2) 0 Kinematic viscosity, v(m/s) 20 100 200. (30 pts) (a) Use MS-Excel to complete the following table. Dry air is a mechanical mixture of nitrogen, oxygen, argon and several other gases in minor amounts. Question: Automatic Zoom 12-3 VISCOSILY Problem 2-8: Consider air at a pressure of 1 atm. To obtain kinematic viscosity (v ny), multiply the measured flow time (tf) by the so-called capillary constant (KC). Chemical, physical and thermal properties of acetone, also called 2-propanone, dimethyl ketone and pyroacetic acid. Email: scientific and engineering data onlineĬalculation of thermodynamic state variables of nitrogen Viscosities of products and chemical species at varying conditions.
