An air compressor takes in air at standard conditions (use 14.7 psia and 70°f) at a negligible velocity. the air is discharged at 115 psia and 125°f with a den- sity of 0.5 lbm/ft 3. the mass fl ow rate out of the 0.5 ft2 discharge pipe is 12 lbm/s. if the compressor input horsepower is 800, find the magnitude and direction (in words) of the heat transfer to/from the compressor in units of btu/s. assume a steady flow. draw a control surface for the calculation.
