The system included two MidMark model P-32 air compressors. are sometimes used for compressed air, while sizes more than 2 in. Gravity and airflow will then carry condensate to the low points where drop leg should be installed to allow for removal at to accessible drop legs and drain points. The compressed air is delivered to the air dryer where water and a small amount of oil is removed. I would like to know how other Jurisdictions treat this issue. Compressors are similar to pumps, both increase the pressure on a fluid and both can transport the fluid through a pipe. Whether you are in the market to purchase, need repairs or want to rent a compressed air or vacuum system, United Compressed Air Inc. They are available in a range from 25 cfm to 3000 cfm at pressure up to 600 psig in single, 2-stage & 3-stage designs. This can cut the overall pipe length to a point in half that reduces pressure drop. inlet (suction) pressure: Pressure at or near the inlet flange of the compressor. We don’t favor this. compressed air systems. Just push the tubing into the fitting until fully seated. The Reynolds number for a pipe flow can be found by: Re = rho V D / mu with rho being density (kg / m3), V being flow speed (m/s), D being the pipe diameter (m), and mu being the dynamic viscosity (N s / m^2).
