Calculate the Btus required to heat an oil tank that measure
Calculate the Btu\'s required to heat an oil tank that measures 5\' times 2.5\' times 3\' from 60degF to 140degF, if rho = 55 lb_m/ft^3 and c(specific heat) = .5 Btu/lb-degF.
Solution
heat required = mass*specific heat* temperature difference
mass = density*volume = 55*5*2.5*3=2062.5 lb
c= 0.5 btu/lb F
Temp= 140-60=80F
Q= 2062.5*0.5*80=82500 Btu
