Determine the final pressure, in bar, and the work, in kJ. 19 One kilogram of water initially at 160°C, 1.5 bar, undergoes an isothermal, internally reversible compression process to the saturated liquid state. Determine the work and heat transfer, each in kJ. Sketch the process on p-v and T-s coordinates. Associate the work and heat transfer with areas on these diagrams. gas within a piston-cylinder assembly undergoes an isother- wal process at 400 K during which the change in entropy is -0.3 kJ/K. Assuming the ideal gas model for the gas and negligible kinetic and energy effects, evaluate the work, in kJ. 6.18 One kg mass of water initially a saturated liquid at 100 kPa X = 80%.
