Question

A volcanic plume puts ash into the atmosphere to a

science chemistry

Answer 1

Answer #1

Solution:

Settling velocity is used to determine the approximate time for the ash particle to settle down from 10000m,

18μ particle diameter fluid viscosity

V_s = (9.81* (1000-0.7)* 40 E-06 ) / 18 = 0.02178 m/s

so it takes 33 hours approx for the ash particle to settle down

Option (B) 53 hours.

A volcanic plume puts ash into the atmosphere to altitude of 10000m. The characteristic ash particle is a sphere with a diameter of 40 um and has a density of 1000 kg/m3. Consider a single ash particle in isolation that is travelling vertically at its terminal velocity (i.e. no acceleration). Assume the density and kinematic viscosity of the air are independent of altitude and is given ,-07kg/m3 and v= 1.5 x 10° m2/s. The drag coefficient is given by Stokes'...
