100 kg/hr of air is compressed from 110 kPa and 255 K (where it has an enthalpy of 489 kJ/kg) to 1000 kPa and 278 K (where it has an enthalpy of 509 kJ/kg). The exit velocity of the air from the compressor is 60 m/s. The inlet velocity is very small and can be neglected. The process is adiabatic and there is no change in height during the process. a) Label all known information on the diagram. State if...

s total) An adiabatic air compressor is powered by a direct-coupled (35 pts total) adiab atic steam turbine. This same turbine also simultaneously drivesa nerator (see next page). Steam enters the turbine at 12.5 MPa and 500 degrees C at a rate of 50 kg/sec, and exits at 10kPa with a quality of 0.92. Air enters the compressor at 98 kPa and 295 K at a rate of 17 kg/sec and...

A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...
