Steam enters a turbine at 35 m/s and specific enthalpy of 3500 kJ/kg. The steam leaves the turbine as a mixture of vapor and liquid having a velocity of 50 m/s and a specific enthalpy of 2500 kJ/kg. If the flow through the turbine is steady, adiabatic, and changes in elevation are negligible, calculate the work output per unit mass (kJ/kg) for the turbine.

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.
