Regarding the functioning of a steam turbine, why is it advisable to keep moisture in the inlet as low as possible?

Explanation:
Wet steam entering a turbine brings liquid droplets into the flow. When these droplets strike the turbine blades, they impart energy to the blade surfaces and cause erosion and pitting over time. This wear accumulates and can shorten blade life and reliability. Keeping moisture in the inlet as low as possible minimizes these droplet impacts, preserving blade integrity and extending service life. While corrosion and efficiency effects can be concerns in other contexts, the most direct and impactful reason here is to reduce erosion from liquid droplets hitting the blades.
