Using Interactive Therodynamics software, do the following problems.

Submit your IT code and results for each problem.

Find the properties tool under tools. For air, find the equation for enthalpy from temperature and write it down. Then copy and paste it into the user workspace. For a temperature of 380K, what is the enthalpy of air? Note: you will need to modify the units (click on units radio button) to match the problem in the IT software and then click the solve radio button. Now compare the answer to the value found in table A-22. Comment on your results.

2. Click the properties radio button and calculate the entropy for saturated water at 6 bars and a quality of 1.0 Compare with the value found in the tables in the back of the book and comment on your results.

3. Find the enthalpy of air at 285K and 100kPa. Compare with the value found in the tables in the back of the book and comment on your results.
