3. Schematic Drawing

4. Data Collection

5. humidity (wet & dry bulb temp) ambient temperature exiting air velocity

6. Equipment humidity- sling psychrometer ambient temp- anemometer air flows- turbine anemometer water temperature- thermometer psychrometric chart

7. Psychrometer Readings

8. Exit Airflow Data

9. Volumetric Airflow

10. lbs. of water/lbs. of dry air

11. Enthalpy

12. Formulas q = m ( hout - hin ) mass flow rate = flow rate of air / volume per mass of dry air volumetric flow rate = n (  r2 / 4 )

13. Calculations Total Volumetric Airflow 2,711,065 cubic ft/min Avg Mass Flow Rate 9,420,625 lbs. DA/min Heat Rejected to Atmoshpere 48,346 btu/day
