Carbon dioxide gas is compressed at steady state from a pressure of 20 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 2500 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 * Your answer is incorrect. Determine the flow area at the inlet, in ft². A₁ = i 0.1646 ft²

Question
Transcribed Image Text:Carbon dioxide gas is compressed at steady state from a pressure of 20 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 2500 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
* Your answer is incorrect.
Determine the flow area at the inlet, in ft².
A₁ = i
0.1646
