Gases, the L-R Rule

Example 8.8 Estimate the value P = f i for water vapor in the hypothetical state of 1 atm pressure and 68°F, using the little EOS. 

Using the above values of 7/ and Py, the value of o from Table A.1, and applying the result for the little EOS from Example 7.1, we find 

For hand calculation the L-R rule is normally satisfactory. If we are writing a computer program to do many
