Simplifying Rear Axle Ratio of Semis / Trucks / Primemovers

5.7:1 means
5.7 turns of Drive Shaft for a turn of Rear Axle
higher the value (ratio, 6.01) higher the torque, lower the fuel economy, engine has to work harder on higher vehicle speeds.
lower the value (ratio, 4.33) lower the torque, higher the fuel economy, engine remains at ease on higher vehicle speeds.

Air Compressors with a capacity of more or equal to 1000 cfm are used primarily for Air Pigging to clean out built pipelines to insure smooth efficient and clean flow of natural gas to the end user before final commissioning.
