28. A centrifugal air compressor compresses 200 cfm from 12 psia to 90 psia. The initial specific volume is 12.6 and final specific volume is 3.25 If the inlet suction lite is 4" L.D. and the discharge line is 2.5" I.D. Determine ft-lh (a.) The change in flow energy between the boundaries in Ib (b.) the mass flow rate in and min (c) the change in velocity in fps.
