Question 251Steam Plants - Assistant Engineer
70% to passWith an increase in the saturation pressure of a fluid, the value represented by line "5" on the graph will _______________. Illustration SG-0001
Aincrease the number of BTU's per pound, per change in degree of temperature
Bdecrease the number of BTU's per pound, per change in degree of temperature
Cremain virtually the same
Drepresent an increase in the latent heat of condensation
AI Explanation
The correct answer is C) remain virtually the same. The saturation pressure of a fluid is the pressure at which the fluid transitions from a liquid to a gas (or vice versa) at a given temperature. An increase in the saturation pressure does not affect the value represented by line "5" on the graph, which corresponds to the latent heat of condensation. The latent heat of condensation is a fundamental property of the fluid and remains constant regardless of changes in saturation pressure. The other options are incorrect because they do not accurately describe the effect of increased saturation pressure on the latent heat of condensation.
