volume to Reservoir engineers transfer a crude oil with at 30 C, and 9 kPa, and 200 m tank by expand it at constant temperature until the pressure become 3 kPa, and V. Then the oil cooled at constant volume and the pressure 1 kPa. Find the mass, V2, V3 and T3 values. Take R=260 J/kg. K. Draw the P-V diagram of each process
