Approximately spherical particles of diameter 150? and density 2650 kg/m3 settle through a liquid of density 1097 kg/m3 and dynamic viscosity 3.8 mPa s. The volume fraction of particles is 30% in a container of internal diameter 2 cm

Calculate: a)The absolute settling velocity that is apparent to the stationary observer in the lab frame. b)The slip velocity (Us) between solid and liquid phases. c) The superficial velocity of the particles in the lab frame.

A liquid of density 1.33 × 103 kg/m3 flows steadily through a pipe of varying diameter and height. At location 1 along the pipe the flow speed is 9.09 m/s and the pipe diameter is 10.9 cm. At location 2 the pipe diameter is 14.3 cm. At location 1 the pipe is 9.75 m higher than it is at location 2. Ignoring viscosity, calculate the difference between the fluid pressure at location 2 and the fluid pressure at location 1.

An 80 kg skydiver falls through air with a density of 1.15 kg/m3 . Assume that his drag coefficient is C=0.57. When he falls in the spread-eagle position his body presents an area A1=0.94 m2 to the wind, whereas when he dives head first, with arms close to the body and legs together his area is reduced to A2=0.21 m2 . What are the terminal speeds in both cases?
