Carbon dioxide gas is compressed at steady state from a pressure of 16 lb/in² and a temperature of 32°F to a pressure of 50 lb/in² and a temperature of 100°F. The gas enters the compressor with a velocity of 30 ft/s and exits with a velocity of 80 ft/s. The mass flow rate is 3000 lb/hr. The magnitude of the heat transfer rate from the compressor to its surroundings is 5% of the compressor power input. Use the ideal gas model with c₂-0.21 Btu/lb-ºR and neglect potential energy effects. Determine the flow area at the inlet, in ft², and the power required by the compressor to work, in horsepower. Step 1 Determine the flow area at the inlet, in ft². Your answer is correct. A₁- 0.2077 Hint Step 2 * Your answer is incorrect. W ft² Determine the power required by the compressor -16.173 hp ork, in horsepower. Attempts: 2 of 4 used

Carbon dioxide gas is compressed at steady state from a pressure of 16 lb/in² and a temperature of 32°F to a pressure of 50 lb/in² and a temperature of 100°F. The gas enters the compressor with a velocity of 30 ft/s and exits with a velocity of 80 ft/s. The mass flow rate is 3000 lb/hr. The magnitude of the heat transfer rate from the compressor to its surroundings is 5% of the compressor power input. Use the ideal gas model with cp -0.21 Btu/lb-ºR and neglect potential energy effects. Determine the flow area at the inlet, in ft², and the power required by the compressor to work, in horsepower. Step 1 Determine the flow area at the inlet, in ft². A₁- 0.2077 Hint Your answer is correct. Step 2 * Your answer is incorrect. Win = ft² Determine the power required by the compressor to work, in horsepower. -16.173 hp Attempts: 2 of 4 used
