A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism.They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications such as chillers, or to operate high-power air tools such as jackhammers and impact wrenches. You may get a doubt that, what if we get two roots as negative, then in that case consider the lower value(for better results). Example of blower sizing calculation : a study shows that for a dilute phase vacuum conveying, an air flowrate at pick-up of 350 m3/h is required under a pressure drop of the line of 300 mbar. Now days we have computer programs that can calculate positive displacement blower performance. Also, if the blower is working in a different environment (low atmospheric pressure from high altitudes, or moving a gas other than air), the blower performance curve shifts.
