A boiler is used to generate steam. Water enters the boiler, saturated at 60°C at an unknown flow rate. Superheated steam exits at 10 bar and 262°C. The energy input of the boiler is 420 KW. Determine the flow rate of water through the boiler, in kg/hr. Neglect kinetic and potential energy changes.
When two systems are in contact, the entropy transfer from the warmer system is equal to the entropy transfer into the cooler one at the point of contact. That is, no entropy can be created or destroyed at the boundary since the boundary has no thickness and occupies no volume.

Steam enters a turbine at 100 bars and 400°C. At the exit the pressure is 1.0 bar and the entropy has increased by 0.600 kJ/kg K under adiabatic conditions. The changes in kinetic and potential energies may be neglected. (a) Determine the work, in kJ/kg. For the same initial conditions and final pressure the turbine is now run without insulation.
