The terminal velocity (π£) of a spherical inclusion of diameter D = 50 micrometers rising in liquid steel is_______ (in mm s-1 to two decimal places).
Assume Stokes law; i.e., drag force πΉπ = 3πππ·π£, where π is the viscosity of steel. Given: Density of liquid steel = 7900 kg m-3; Viscosity of liquid steel = 0.0079 Pa s; Density of the inclusion = 2500 kg m-3; Acceleration due to gravity = 9.8 m s-2.
