Unformatted text preview: UNIT 2 INTRINSIC FLUID PROPERTIES Chapter 1 from Houghtalen et al. (2010) What properties describe the differences between fluids? Homsy et al 2007 Mass Density ( ) The mass density ( ) or just density is defined as mass per unit volume. Units of slugs per cubic foot (slugs/ft 3 ) or kilograms per cubic metre (kg/m 3 ) V M = function CalcWaterDensity(T) % lookup and plotting function for water density versus temperature % T is a vector of water temperatures water.temp = [100 80 60 40 30 25 22 20 15 10 4 0 -10 -20 -30]; water.density = [958.4 971.8 983.2 992.2 995.6502 997.0479 997.7735 998.2071 999.1026 999.7026 999.9720 999.8395 998.117 993.547 983.854]; % yi = interp1(x,Y,xi,method) rho = interp1(water.temp,water.density,T,'spline'); plot(T,rho); xlabel('temperature (\circ C)'); ylabel('density (m^3 s^{-1})'); title('Density of Water'); Lake temperature s Lake Turnover Specific Weight ( ) (or Weight Density) [F L-3 ] or N m-3 or lb f ft-3 V W = Defined as the unit weight per volume: g = Specific Gravity defined as the ratio of the specific weight of the substance to the specific weight of water w S =- dimensionless Standard Conditions Fluid properties are typically referenced to a standard temperature and pressure. Typically use 4 o C as a standard temperature. Standard pressure is the sea level pressure of a standard atmosphere (approximate mean conditions at 40 latitude) and is equal to 101.3 kPa. With the international system of units the properties of water are: 3 4 3 3 4 9806 1000 00 . 1 m N m kg cm g C C o o = = = Example problem 1 A tank containing 1200 kg of glycerine has a volume of 0.952 m 3 . Find: 1. The weight of the glycerin; 2. The mass density of the glycerin; 3. The specific weight of glycerin; and 4. The specific gravity of glycerin. Specific volume ( ) the volume occupied by a unit mass of a fluid (m 3 /kg) 1 = v reciprocal of density Bulk or Elastic Modulus (E...
