Steam at 15 bar, 540 °C, 60 m/s enters an insulated turbine operating at steady state and exits at1.5 bar, 89.4 m/s. The work developed per kg of steam flowing is claimed to be (a) 606 kJ/kg, (b)765.9 kJ/kg. Can either claim be correct? Explain. textbook
Answers: 3
![w_{out} = 3562.10\,\frac{kJ}{kg} - 2693.10\,\frac{kJ}{kg}+\frac{1}{2}\cdot [(60\,\frac{m}{s} )^{2}-(89.4\,\frac{m}{s} )^{2}] \cdot (\frac{1\,kJ}{1000\,J} )](/tpl/images/0549/2929/ae5ca.png)
