  1. Challenger Center Cooling Tower Enev/Ench 435 September 23, 2008 Performed By: Dianah Dugan Alex Saputa

  2. Contents • Block Diagram • Schematic • Equipment • Data Collection • Results • Conclusion

  3. Block Diagram of Cooling Tower Air Inlet Air Outlet CT unit T h q P H T P

  4. Cooling Tower Schematic Exhaust Outside Intake OutsideIntake Inside Intake

  5. Schematic of Exhaust Fan 0.22 ft 0.72 ft 1.22 ft *Distances measured from center of fan

  6. Equipment • Anemometer • Yard Stick • Ladder • Sling Psychrometer • Psychrometric Chart

  7. Radial Dependence of Temperature

  8. Radial dep vs temp expt 1

  9. Average Velocity Per Cross-Section

  10. Average Cross-Sectional Air Flow

  11. Average Volumetric Flow

  12. Volumetric Flow • How to solve for with formulas and trapezoidal rule • Don’t forget results from expt 1

  13. Volumetric Flow (cu. ft/min) • results

  14. Dry Bulb Air Intake Temperature

  15. Humidity • Tell about relative humidity (data taken) • Absolute humidity being same in and out • RH from psychrometric chart • enthalpy

  16. Mass Flow Rate *check density at exit temp Mf = (density)*(area)*(velocity)

  17. Heat Generated

  18. Compressor Run Times

  19. Block Diagram • With values that have been solved for

  20. Conclusions • Temperature is highest at the center of the fan and lowest surrounding the edges • Velocity is the least in the center of the exhaust

  21. Comments
