So, let''s do the math. The one-horsepower air motor outputs about 0.75 kW of shaft power. To produce this power: A lossless compressor must consume about 7.5 kW (30 x 25/100 = 7.5 kW) Leaks increase the power required to 9.75 kW (7.5 kW x 1.3= 9.75 kW). Overcoming pressure drop increases the power further to 10.5 kW (9.75 x …
