1 kg of Nitrogen gas at 1 bar and 300K is compressed to 5 bar and 400K. Find i) Index of process ii) Work Transfer iii) Heat transfer iv) Change in internal Energy

1) Air is compressed under Constant Entropy Process from 10 Psia, 3 ft3, 90°F to 50 Psia. Find the following:       a) Final volume in ft3.       b) Final temperature in °F.       c) Work non-flow in BTU. From the problem above use all PVT values, What if the 1lbm of air is compressed under quasi-static process (n=1.27). Find the following:       d) Work non-flow in BTU.       e) Heat in BTU.

2.0 lb of water inside a piston-cy inder assembly undergoes the following two processes in series Process 1-2: Contant pressure cooling from a saturated vapor at p1 = 170 psi until x2 = 80%. Process 2-3: Constant volume heating to a saturated vapor. There are no changes in kinetic or potential energy. a) [2 pts] Find the specific volume for state 1 in ft3/lb. b) [2] Find the specific volume at state 2 in At3/b
