Q

If a quantity of saturated steam consists of 90 percent steam and 10 percent moisture, the quality of the mixture is __________.

🔍 Key Concepts

• Meaning of steam quality (also called dryness fraction) for a saturated steam-water mixture • How to convert percent by mass into a decimal fraction • Relationship between mass of dry steam and total mass of the mixture

💭 Think About

• When we say 90 percent steam and 10 percent moisture, what are we comparing? Volume, mass, or something else for steam quality? • How is steam quality usually expressed in engineering problems: as a percentage or as a decimal between 0 and 1? • If a mixture were 100 percent dry steam with no moisture, what would its quality be, and how does that help you scale back to 90 percent?

✅ Before You Answer

• Confirm that quality = (mass of dry saturated steam) / (total mass of mixture) • Check that 90 percent is expressed correctly as a decimal for your final choice • Verify that a quality of 1 would mean completely dry steam with 0% moisture.
