Liquid 3 The Goal Is To Determine The Drag Force On A 50 Cm Diameter Sphere Moving Through A Bath Of Sae 10w Oil At 20 1 (132.37 KiB) Viewed 33 times

Liquid 3) The goal is to determine the drag force on a 50-cm-diameter sphere moving through a bath of SAE 10W oil at 20°C. A scale model of the sphere 10 times smaller is made and tested in glycerin at 20°C and at a velocity of 2 m/s. The measured drag force on the model is 100 N. For similar conditions, what are the velocity and drag of the actual sphere in SAE 10W oil? Ammonia Benzene Carbon tetrachloride Ethanol Ethylene glycol Freon 12 Gasoline Glycerin Kerosine Mercury Methanol SAE 10W oil SAE 10W30 oil SAE 30W oil SAE 50W oil Water Seawater (30%) Dimensional analysis shows the following relation between two Pi groups FD relevant to the problem: pvzpz = frems). Here, F, is the drag force, p and u are fluid density and dynamic viscosity, and V and D represent velocity and diameter, respectively. Properties of common liquids at 1 atm and 20°C are shown in the table. p, kg/m kg/m.s) 608 2.20 E-4 881 6.51 E-4 1,590 9.67 E-4 789 1.20 E-3 1.117 2.14 E-2 1,327 2.62 E-4 680 2.92 E-4 1,260 1.49 804 1.92 E-3 13.550 791 5.98 E-4 870 1.04 E-17 876 1.7 E-1 891 2.9 E-1 902 8.6 E-17 998 1.00 E-3 1,025 1.07 E-3 1.56 E-3
