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.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
