Question

4) (5 pts) A 140 ft2 vacuum drum filter cost $8000 in 2007. Estimate what a 100 ft2 vacuum drum filter cost in 2016? Assume the CEPCI index in 2016 was 540 CEPCI Values Annua Index: 2006 = 499.6 2007 525.4Equipment/Facility 2008 = 575.4 | Blower, centrifugal 2009 = 521.9 | Crystallizer, vacuum batch 2010 550.8Dryer. drum, single atmospheric 2011 = 585.7 | Filter, vacuum rotary drum 2012 584.6 Motor 2013=567.31 Reactor, 300 psi TABLE 2-1 Example Power-Sizing Exponent Values Power-Sizing Exponent Size Range 10,000-100,000 ft*/min 200-2100 hp 500-7000 f2 10-100 f2 20,000-70,000 ft/nin 10-1500 ft2 0.05-20 million gal/day 5-20 hp 100-1000 gal 100-40,000 gal 0.59 0.32 0.37 0.40 Compressor Fan, centrifugal 0.48 1.13 0.69 0.56 0.57 Lagoon, aerated | Tank, atmospheric, horizontal

Explanation / Answer

We use formula
consider calculation for 140 ft^2
(cost at B)/(cost at A)= (index at B)/(index at A)
(cost in 2007)/(cost in 2016)= (index in 2007)/(index in 2016)
($8000)/(cost in 2016)= (525.4)/(540)
(cost in 2016)/($8000)= (540)/(525.4)
(cost in 2016)/($8000)= 1.0277883517320137038446897601827
(cost in 2016)= 1.0277883517320137038446897601827($8000)
(cost in 2016)= 8222.3068138561096307575180814617
(cost in 2016)= 8222.307

So now we know that 140 ft^2 vaccum drum filter costs $8222.307 in 2016
then 1 ft^2 vaccum drum filter costs $8222.307/(140) in 2016
then 100 ft^2 vaccum drum filter costs $(8222.307/140)*100 in 2016
=$5873.0764285714285714285714285714

So then answer is that cost of 100 ft^2 vaccum drum filter in 2016 is approx $5873.08
