Example 7.5-3 Energy Balance on a Steam Turbine Steam at 10 bar absolute with 190°C of superheat is fed to a turbine at a rate in = 2000 kg/h. The turbine operation is adiabatic, and the effluent is saturated steam at 1 bar. Calculate the work output of the turbine in kilowatts, neglecting changes in kinetic and potential energy.

Even though the pressure has doubled, the values of Û and Ĥ change by much less than 1%. Similar results would be obtained for liquid water. The conclusion is that when you need a value of Û or Ĥ for water (or for any other species) at a given T and P, you must look it up at the correct temperature-interpolating if necessary but you don't have to find it at the exact pressure.
