A spherical particle having a diameter of 9.3 x 10-3 inches and a specific gravity of 1.85 is placed on a horizontal screen. Air is blown through the screen vertically at a temperature of 20 oC and a pressure of l atm. Calculate the following:

(a) Velocity required to just lift the particle.
(b) Particle Reynolds number at the condition of part (a).
(c) Drag force.
(d) Drag coefficient CD.

Given;

Viscosity of air = 1.23 x I0 -5 lbm/ft.s

Density of air = 7.52 x 10-2 lbm/ft3

Gravitational constant (gc) = 32.2 lbm.ft/lbr.s2
