With increase in steam pressure, its specific volume decreases ____________________?
Correct answer: A. Rapidly first and then slowly
- A. Rapidly first and then slowly
- B. Linearly
- C. Slowly first and then rapidly
- D. Exponentially
Explanation
For saturated steam, specific volume falls steeply as pressure first increases, then the rate of decrease becomes smaller over much of the normal pressure range. Hence the usual description is rapid decrease first and slow decrease later.
