The steam enters a steam turbine system at 1000psi and 1000F. It leaves the turbine at 1 psi. The turbine is separated into four stages. The first 2 stages are impulse stages. The last two stages are reaction stages. The turbine has pitch diameters of 30,40, 50 and 60 inches for these 4 stages. You may assume a nozzle efficiency of 0.9 , a velocity coefficient of 0.95 , and inlet angle of 20. Design the turbine blades for these 4 stages. Design parameters should be adjusted to obtain optimal design. USING THE FIRST TWO STAGES, SHOW THE CALCULATIONS TO OBTAIN THOSE RESULTS. The steam enters a steam turbine system at 1000psi and 1000F.
