Q1: The settlement velocity of a solid (diameter 0.5 mm, specific gravity 1.75) in water having temperature 10°C, isA
213.5 cm/sec
B
313.5 cm/sec
C
413.5 cm/sec
D
500 cm/sec
ANS:B - 313.5 cm/sec The settlement velocity of a solid particle in a fluid can be calculated using Stokes' law, which states that the settling velocity (vs) of a spherical particle in a viscous fluid is given by: vs=2/9(r^p2)(Pp−ρf)g / η Where:
