AI Explanation
The correct answer is B) a decrease in the length of line 4. When the saturation pressure of water is increased, the relative values shown on the illustrated graph of SG-0001 will change. According to the information found in the steam tables of SG-0004, an increase in saturation pressure will result in a decrease in the length of line 4, which represents the saturation line on the graph. The other options are incorrect because: A) there would be a change to the length of line 4, not no change; C) the height of line 4 would change, not remain constant; and D) the height of line 4 would decrease, not the length.
