Steam enters an adiabatic turbine at 8 mpa and 500°c at a rate of 3.3 kg/s and leaves at 20 kpa. if the power output of the turbine is 2.5 mw, determine the temperature of the steam at the turbine exit. neglect kinetic energy changes.

Aseries piping system conveys methyl alcohol. the system consists of 70 m of 1- nominal pipe follow by 50 m of 2-nominal pipe, both schedule 40 commercial steel. the 1-nominal pipe contains 3 90° elbows (regular) anda fully open gate valve, all threaded. the pressure drop through the system is 150 kpa. determine the volume flow rate through the system that is horizontally laid.
