Circulating a steady state turbine 20000 kg / h of steam at 4 bar entering and 440 ° C and leaves at 0.20 bar and 90% quality. A heat of 20 kJ / kg is lost. The inlet has a diameter of 8 cm and the output section is rectangular, of dimensions 0.9 m by 1.1 m. Calculate (a) the change in kinetic energy, (b) the power output. Expressing both results in kilowatts.
