2. 4 CFM per Horsepower on a 100 psi air compressor 

3. Each psi pressure drop equals 0.5% in Horsepower 

4. 7.48 gallons per cubic foot 

5. The heat load on an air cooled compressor is HP x 2545 BTU/HR 

6. 60% of condensate is removed after the aftercooler 

7. 96% is removed after the refrigerated air dryer 

8. Pressure and flow are inversely proportionate 

9. Every 20 degree increase in discharge temperature increases moisture content by 50%
