A window is left slightly open while the air conditioning system is running. The air conditioning blower develops a pressure of 2 in. $\mathrm{H}_{2} \mathrm{O}$ (gage) inside the house, and the window opening measures $1 / 8$ in. $\times 20$ in. Neglecting friction, what is the flow rate of air through the opening in scfm $\left(\mathrm{ft}^{3} / \mathrm{min}\right.$ at $\left.60^{\circ} \mathrm{F}, 1 \mathrm{~atm}\right)$ ?
