Air flows in a horizontal 100-ft-long, 24-in. \(\times 24\)-in. duct at the rate of \(5000 \mathrm{ft}^{3} / \mathrm{min}\). The air then flows through an expansion into \(200 \mathrm{ft}\) of 36-in. × 36-in. duct. The expansion has a loss coefficient of 0.80, based on the higher inlet velocity. Calculate the static pressure change across the expansion and the static pressure loss across the entire duct system. The duct is made of galvanized sheet metal. Use a constant air density of \(0.0024 \mathrm{slug} / \mathrm{ft}^{3}\).
