An adiabatic turbine in a steam generating plant receives steam at a pressure of 7.0 Mpa and 550°C and exhausts at 20 Kpa. The turbine inlet is 3m higher than the turbine exit; the inlet steam velocity is 60 m/s. What is the pressure of the steam at the turbine exit? A) 7.0 Mpa B) 20 Kpa C) 550°C D) 60 m/s
