Answer to Question #56998 in Thermal Power Engineering for Mark Mildane B. Samson
2.) The flow rate through a steam nozzle is 450 kg/h. The initial and final pressures are 1400 and 14 kPa, respectively. THe initial and final velocities are 150 and 1200 m/s, respectively. If there is no heat transfer, calculate the change in enthalpy.
3.) Steam expands adiabatically through a nozzle from 1400 to 14 kPa. The initial and final enthalpy values are 3300 and 2800 kJ/kg, respectively, and the initial velocity is very low. Determine the final velocity.
