Unformatted text preview: Chapter 2 Fluid Properties Problem 2.1 Calculate the density and speci g31 c weight of nitrogen at an absolute pressure of 1 MPa and a temperature of 40 g114 C. Solution Ideal gas law g29 = g115 g85g87 From Table A.2, g85 = 297 J/kg/K. The temperature in absolute units is g87 = 273 + 40 = 313 K. g29 = 10 6 N/m 2 297 J/kgK × 313 K = 10 g61 75 kg/m 3 The speci g31 c weight is g16 = g29g106 = 10 g61 76 kg/m 3 × 9 g61 81 m/s 2 = 105 g61 4 N/m 3 5 6 CHAPTER 2. FLUID PROPERTIES Problem 2.2 Find the density, kinematic and dynamic viscosity of crude oil in traditional units at 100 o F. Solution From Fig. A.3, g26 =6 g61 5 × 10 g3 5 ft 2 g64 s and g86 = 0 g61 86 g61 The density of water at standard condition is 1.94 slugs/ft 3 g62 so the density of crude oil is g61 86 × 1 g61 94 =1 g61 67 slugs/ft 3 or 1 g61 67 × 32 g61 2 =53 g61 8 lbm/ft 3 g61 The dynamic viscosity is g29g26 = 1 g61 67 × 6 g61 5 × 10 g3 5 =1 g61 09 × 10 g3 4 lbf · s/ft 2 g61 Problem 2.3 Two parallel glass plates separated by 0.5 mm are placed in water at 20Two parallel glass plates separated by 0....
