A certain room measures 15 ft by 10 ft by 8 ft. (a)
Chapter , Problem 7.44(choose chapter or problem)
A certain room measures 15 ft by 10 ft by 8 ft.
(a) Compute the thermal capacitance of the room air using \(c_{p}=6.012 \times 10^{3} \ \mathrm{ft}-\mathrm{lb} / \text { slug }-{ }^{\circ} \mathrm{F}\) and \(\rho=0.0023 \text { slug } / \mathrm{ft}^{3}\).
(b) How much energy is required to raise the air temperature from \(68^{\circ} \mathrm{F}\) to \(72^{\circ} \mathrm{F}\), neglecting heat transfer to the walls, floor, and ceiling?
