A steam turbine can be modeled as an is entropic expansion. The incoming steam is super heated
Question:
A steam turbine can be modeled as an is entropic expansion. The incoming steam is super heated at an initial temperature T+ and pressure p+. After expansion, the exhausted steam is at temperature T−. A high-performance turbine cannot tolerate low-quality steam because the water droplets degrade its mechanical components. Suppose that T− = 40 ◦C and that the turbine requires χ ≥ 0.9 throughout the expansion process. If the high-pressure system is rated to 5 MPa, what is the minimum possible initial temperature of the steam?
