Data Collection

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

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

Psychrometer Readings

Exit Airflow Data

Volumetric Airflow

lbs. of water/lbs. of dry air

Enthalpy

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

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
