question

A pipe of diameter 1.1 ft narrows to a diameter of 0.8 ft. Air moves through it at a massflowrateof 6.1 slugs/sec. If at the larger diameter a pressure of 110 psig and a temperature of 75°F exist, calculate the pressure, velocity, density, and temperature in the smaller section.

options

  1. Pressure = 94.0psia, Velocity = 775 ft/sec, Density = 0.0182 slugs/ft^3, Temperature = 65°F
  2. Pressure = 105psia, Velocity = 680 ft/sec, Density = 0.0178 slugs/ft^3, Temperature = 70°F
  3. Pressure = 110psia, Velocity = 650 ft/sec, Density = 0.0196 slugs/ft^3, Temperature = 75°F
  4. Pressure = 95.0psia, Velocity = 700 ft/sec, Density = 0.0175 slugs/ft^3, Temperature = 40°F
  5. Pressure = 92.0psia, Velocity = 760 ft/sec, Density = 0.0185 slugs/ft^3, Temperature = 50°F
  6. Pressure = 98.0psia, Velocity = 735 ft/sec, Density = 0.0165 slugs/ft^3, Temperature = 38°F
  7. Pressure = 102psia, Velocity = 750 ft/sec, Density = 0.0168 slugs/ft^3, Temperature = 60°F
  8. Pressure = 97.5psia, Velocity = 690 ft/sec, Density = 0.0170 slugs/ft^3, Temperature = 42°F
  9. Pressure = 100psia, Velocity = 720 ft/sec, Density = 0.0180 slugs/ft^3, Temperature = 45°F
  10. Pressure = 89.0psia, Velocity = 715 ft/sec, Density = 0.0190 slugs/ft^3, Temperature = 55°F
