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
