During a reversible non-flow process, a cylinder containing 0.075 kg of fluid having pressure of 1.2 bar, a volume of 0.07 m3 and specific internal energy of 180 kJ/kg undergoes a steady polytropic compression process. The steady final pressure , volume and specific internal energy are 9.5 bar, 0.0125 m3 and 350 kJ/kg respectively.

Calculate

  1. The compression index n
  2. The work required for the compression
  3. The quantity and direction of heat energy                              

Assume it was a steady isothermal (hyperbolic) compression process with final volume 0.0125 m3. Calculate

  1. Pressure at the final state
  2. The work required for the compression
  3. The quantity and direction of heat energy
