1. Find the specific entropy generation in the shock of the previous problem.
2. Steam at 600 kPa, 300?C, is fed to a set of convergent nozzles in a steam turbine. The total nozzle exit area is 0.005 m2, and the nozzles have a discharge coefficient of 0.94. The mass flow rate should be estimated from the pressure drop across the nozzles, which is measured to be 200 kPa. Determine the mass flow rate.
