a compressed air drill requires 0.25 kg/s of air at 650 kpa (gage) at the drill. the hose from the air compressor to the drill is 40 mm inside diameter. the maximum compressor discharge gage pressure is 670 kpa; air leaves the compressor at 40oc. neglect changes in density and any effects of hose curvature. calculate the longest hose that may be used. note: neglect minor losses and elevation differences. further, treat air as an ideal gas with r
