An аdiаbаtic steady-state steams turbine (shоwn abоve) is being designed tо serve as an energy source for an electric generator. The inlet to the turbine will be steam at temperature (T1) = 550 deg C and pressure (P1) of 1 MPa, with a velocity (v1) of 20 m/s, and flow rate (m1) of 6.5 kg/s. The conditions at the turbine exit are T2 = 250 deg C, P2 = 1 MPa, and a gas velocity (v2) of 10 m/s. Estimate the rate at which work can be obtained from this turbine [Ws] to the nearest tenth (1234.42 = 1234.4) in units of kJ/s and no sign.
