Sizing Air Compressor

In order to be able to calculate the correct sizing for an air compressor first I had to calculate the detention time and precise volume of the tank. Next I had to formulate an expression to come up with the air flow requirement for the compressor and tank. However when determining the airflow I also had to account for friction occurring in the various fittings in the tank and those friction coefficients were provided by the manufacturer Baker Tanks. The last step was to determine the hydrostatic pressure through a custom formula provided by Baker Tanks as well and I found the correct sizing of the air compressor to provide 38.4cfm at 8.12 psi. This data led me to conclude that the air compressor needed for this tank needs to fit precisely these specifications to be most efficient.
