What is the percent error in specific volume if the ideal gas model is used to represent the behavior of superheated ammonia at 40°C and 500 kPa? What if the generalized compressibility chart, Fig. D.1, is used instead?

Step 1 of 5
The objective here is to determine the error percentage in two cases:
- If the ideal gas model is used to represent the behavior of superheated ammonia under the given conditions.
- Using the Compressibility chart.
