Steam enters a well-insulated turbine operating at steady state at 4mpa with a specific enthalpy of 3015.4 kj/kg and a velocity of 10 m/s. the steam expands to the turbine exit where the pressure is 0.07 mpa, specific enthalpy is 2431.7 kj/kg, and the velocity is 90 m/s. the mass flow rate is 11.95 kg/s. neglecting potential energy effects, determine the power developed by the turbine, in kw.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
