Q3. Drag measurements were taken for a 5 cm diameter sphere in water at 20°C to predict the drag force of a 1 m diameter balloon rising in air with standard temperature and pressure. Given kinematic viscosity of water (v) = 10 X 106 m²/s and kinematic viscosity of air (v) = 1.46 X 10-5 m2/s. 1. Perform the Buckingham Pi theorem to generate a relationship for Fo as a function of the independent variables. Assume the drag Fo is...
[10 points] A model of a submarine, 1:15 scale, is to be tested at 180 ft/s in a wind tunnel with standard sea-level air, while the prototype will be operated in seawater. Determine the speed of the prototype to ensure dynamic similarity 4. Properties of air: p 2.38x103 slugs/ft3, 3.74 x 107 Ib-s/ ft2 Properties of seawater: 1.99 slugs/ft3JL-2.51 x 10-5 lbs/ ft.
organisms. If we have a sphere moving in a fluid of density ρ and viscosity μ, and the sphere has a radius R and speed r and drag coefficient Co, then the drag and viscous forces are given by these equations: 2. in this problem, we'll estimate which resistive force- viscous force or drag force-dominates for two different The Reynolds number is given by Re ()Rv. For air and water, we can use the densities and viscosities in the table...
1) 2) 3) Oil flows through an 8-inch diameter pipe with a velocity of 18 ft/s. If it discharges into the atmosphere through the nozzle, determine the total force the bolts must resist at the connection AB to hold the nozzle onto the pipe. Assume Yo = 55 lb/ft3.
