Question:

The steam table C-2E has a low pressure of 1 psia, unlike Table C-2, which has a much lower pressure of 0.611 kPa. A need is expressed for the saturation temperature of steam below 1 psia; suppose that only Table C-2E is available. Estimate the saturation temperature of steam at
a) 0.1 psia,
b) 0.2 psia,
c) 0.6 psia using information from Table C-2E.
