As the particle fails downward, "creeping flow' will be established around it. The oil has a density of...
Density p [kg/m2], viscosity - u [kg/ms], surface tension - o (N/m=kg/s2] compressibility K [Pa-kg/ms2] 1. For particles settling in a stationary fluid it is thought that the drag force FD of a small sphere is a function of the settling velocity of the sphere - V, the diameter of the sphere - d, and the density p, and viscosity of the fluid - . Determine the dimensionless relationship(s) between these variables (FD/HVd, pdV/H) 2. (a) The efficiency of a...
3 x 10-6 m2/s, estimate the i) (1 pes.) The kinematic viscosity Reynolds number for the flow around a particle of size on the order of 1 μ m (= 10° m), assuming the velocity of the flow is on the order of 1 cm/s. Would "creeping flow" be a good approximation to the flow? Recall Re pULIp. し μ/ρ of a fluid is about

Stokes' law describes sedimentation of particles in liquids and can be used to measure viscosity. Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density 7.8 x 103 kg/m3, diameter 2.0 mm) is dropped in a container of motor oil. It takes 11 s to fall a distance of 0.65...

solve using paython In fluid flow problems, the flow velocity in a long horizontal pipe depends on the pipe material, pipe geometry and fluid properties in addition to the pump power. For a horizontal pipe with a pump, the friction factor can be obtained from many correlations such as Colebrook-White Equation: 1.1998 5.0452 (6) log Re 28257 -)} (1) 3.7065 7--2 log +58506 (Re)-0.3981 In which, f is the friction factor and is the roughness ratio given by: given by:...
