In order to increase the velocity of steam used as a fluid for a power plant, it was concluded that it needs to pass through a nozzle. The steam at 300C and 2MPa flows at 0.7 kg/s. 12kJ/s of heat is lost during the process and the steam then attains a temperature of 200C and a pressure of 1.4MPa. What would be outlet velocity from the nozzle if its inlet diameter is 6cm? What is the outlet diameter of the nozzle? Properties at inlet H1 = 3023.5 kJ/kg, SV1 = 0.12547 m3/kg and for outlet conditions H2 = 2803.3 kJ/kg, SV2 = 0.14302 m3/kg.
