A piston-cylinder device with a set of stops initially contains 0.6 kg of steam at 1.0 MPa and 400βC. The location of the stops corresponds to 40 percent od the initial volume. Now the steam is cooled. Determine the compression work if the final state is
(a) 1.0 MPa and 250βC and
(b) 500 kPa.
(c) Also determine the temperature of the final state in part b.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
