Limestone (calcium carbonate) particles arestored in 50-L bags. The void fraction of the particulatematter

is .30(liter of void space per liter of total volume) andthe

specific gravity of solid calcium carbonate is 2.93.

a) estimate the bulk density of the bag contents

(kgCaCO3/liter of total volume)

b) estimate the weight (W) of the filled bags. State whatyou

are neglecting in your estimate.

c) the contents of three bags are fed to a ball mill, a

devicelike a clotes dryer containing steel balls. The

tumblingaction of the balls crushes the limestone particles and

turns theminto a powder. The limestone coming out of the mill is

putback into 50-L bags. Would limestone fill three bags, notfill

three bags completely, or fill more than three bags. Explain.
