A steam turbine takes in steam at the rate of 6000 kg/h and its power output is 800 kw. neglect any heat loss from the turbine. Find the change in the specific enthalpy of the steam as it passes through the turbine if (a) the entrance and exit are at the same elevation and the entrance and exit velocities are negligible or (b) the entrance velocity is 50 m/s and the exit velocity is 200 m/s, with the outlet pipe 2.0 m above the inlet.

neglect any heat loss from the turbine. Find
the change in the specific enthalpy of the
steam as it passes through the turbine if (a)
the entrance and exit are at the same
elevation and the entrance and exit velocities
are negligible or (b) the entrance velocity is 50
m/s and the exit velocity is 200 m/s, with the
outlet pipe 2.0 m above the inlet.
