Air is compressed in a piston-cylinder assembly from an initial pressure and temperature of 16 psi and 530 oR to a final volume of 1.25 ft3 The compression process is described by the equation Pv12 = • ' constant. The mass of air is 0.5 Ibm. Assume ideal gas behavior and neglect kinetic and potential energy effects. a) Determine the work in BTU b) Determine the heat transfer in BTU using: • Temperatures and constant specific heat evaluated at 530 oR • Internal energy data from Table A-22E c) Compare the results for (b) and discuss. d) What do the sign conventions for Wand Q mean?
