Answer to Question #280418 in Molecular Physics | Thermodynamics for dandan

Question

Steam enters a turbine stage with an enthalpy of 3500 kJ/kg at 80 m/s and leaves the same stage with an enthalpy of 2900 kJ/kg and a velocity of 110 m/s. calculate the work done by the system. *

Answer 1

$W=(H_1-H_2)+(K_1-K_2)=594.3~\frac{kJ}{kg}.$
