As a result of the water vapor expansion process in 7 bar and 260 oC conditions, it reaches its new state at 4 bar and 200 oC conditions. During the expansion process, the heat transfer between the system and its environment can be considered insignificant, and the kinetic energy of the water vapor at the process inlet in the same way can be neglected. The specific enthalpy of water vapor at 7 bar and 260 oC is 2974 kJ / kg and the specific enthalpy at 4 bar and 200 oC is 2860 kJ / kg. Calculate the exit steam velocity in this case?
